I am working on the multifile uploader, and want to set the upload directory based on a selected questionID (which is the directory name) in my datagrid.
The code can be found here http://pastie.org/784185
Something like this:
I have set myQuestionID (the directory to upload to) so it is bindable (lines 136-137):
[Bindable] public var myQuestionID:int;
In my datagrid I use a change handler (line 539):
change="setQuestionID();"
We set the variable in the setQuestionID function (lines 400-407):
[Bindable (event="questionChange")]
private function setQuestionID():void
{
myQuestionID = questionsDG.selectedItem.QuestionID;
dispatchEvent(new Event("questionChange"));
}
And then try to use it in my uploader script (lines 448-475):
// initUploader is called when account info loads
public function getSessionInfoResult(event:ResultEvent):void{
// Get jsessionid & questionid (final directory) for CF uploader
myToken = roAccount.getSessionToken.lastResult;
// BUG: myQuestion is null in actionscript, but okay in form.
var postVariables:URLVariables = new URLVariables();
postVariables.jsessionid = myToken;
postVariables.questionid = myQuestionID;
multiFileUpload = new MultiFileUpload(
filesDG,
browseBTN,
clearButton,
delButton,
upload_btn,
progressbar,
uploadDestination,
postVariables,
350000,
filesToFilter
);
multiFileUpload.addEventListener(Event.COMPLETE,uploadsfinished);
}
I can see in my MXML that the value binded (line 639):
<mx:Label text="{myDirectory}"/>
and it updates when I click a row in my datagrid. However, if I try to access this myQuestionID value inside any action script it will show as null (0). I know my uploader is working as I can hardcode myDirectory to a known directory and it will upload okay.
I'm really stumped.
The reason questionid = null is that getSessionInfoResult() is called by your init code before the bound value of myQuestionID is set.
So your file uploader (multiFileUpload) is already instantiated with myQuestionID = null.
You need to instantiate/pass the value into the multiFileUpload component after it is set.
Use dataGrid change event to set myDirectory everytime the selection has changed by user. this will update the value of myDirectory properly.
By making someID as Bindable would mostly solve your problem if you dont want to use change event on DG

so I am using JavFX to create a form that stores all the answers in a csv file. I need to create a dropdown menu that allows the users to select an option, which is then recorded in the csv file. I have tried a lot of different options, however I think comboBox is the best option.
I have no problem creating the ComboBox, I only run into problems when it comes to the method to get the value of the box.
Can someone help me find a solution, or suggest what another JavaFX menu I can use?
This is the code I have right now:
public VBox setFamiliar(){
Button button = new Button();
button.setOnAction(e -> toString());
familiarComboBox = new ComboBox<>();
familiarVBox = new VBox();
familiarComboBox.getItems().addAll("Irmão", "Irmã", "Avó", "Avô", "Tio", "Tia", "Pai", "Mãe");
familiarVBox.getChildren().add(familiarComboBox);
familiarVBox.getChildren().add(button);
return familiarVBox;
}
Here I set the ComboBox, this part doesnt seem to have a problem because it appears and I can select an item. I created a separate void toString() method that sets the value of a variable to the current selected item
public void toString(ActionEvent e){
familiar = familiarComboBox.getSelectionModel().getSelectedItem().toString();
}
The problem is then in the get method to get the value that was selected.
public String getIrmao(){
if(familiar.equals("Irmão")){
return "2";
}
return "0";
I also tried to do familiarComboBox.getSelectionModel().getSelectedItem().equals(), and other variations of this combination.
If I understand your requirement -- that when a user makes a choice from the "Familiar" combo box, a value should be written immediately to a CSV file -- you don't need the getIrmao() method. You simply write the value out in the action which you are calling toString(...) (not a good choice of names), but which we will rename to handleFamiliarChange(...).
Now the method becomes
public void handleFamiliarChange(ActionEvent e){
final String familiar =
familiarComboBox.getSelectionModel().getSelectedItem().toString();
FileUtils.writeToCsvFile(familiar.equals("Irmão") ? 2 : 0);
}
where FileUtils.writeToCsvFile(...) is a method that does the file writing. Note that FileUtils is a class you have created to separate out file handling concerns -- your JavaFX view class should only concern itself with views.
I have an XAF application. Most of my Business Objects are based on a baseclass "MyBaseClass" which contains Createdby, ModifiedBy, ... Comments. The Comments field is AllowEdit=false. I only want users to be able to modify the comment thru an action which would allow them to create an entry to which I would prepend their UserName and timestamp.
I don't know how to pop up a window to edit a property (string) within the current object and view.
There are plenty of examples of how to CreateListView but in this case what I wish to edit in the popup is not a separate BO but just a string. Maybe that is my problem(???)
I have the Action Controller and I am not sure how to create the DetailView when I get into the _Execute()
In Winforms XAF I add an action in a view controller.
In the action's execute event I call something like
private void actOpenDetailView_Execute(object sender, SimpleActionExecuteEventArgs e)
{
var application = Controller.Application
var viewId = application.FindDetailViewId(typeof(MyBusinessObject));
application.CreateObjectSpace(typeof(MyBusinessObject));
var detailView = application.CreateDetailView(newObjectSpace, jh, true);
e.ShowViewParameters.CreatedView = detailView;
e.ShowViewParameters.TargetWindow = TargetWindow.NewWindow;
}
I haven't tried that in Blazor.
Short Version: I want to have my Copy button in a table to be able to grab the values from an existing entry and populate those into a "Create Entry" Page Fragment. This way users don't have to reenter all the data when making a new entry.
Long Version:
I have two buttons added the rows in my table: Edit and Copy.
The Edit Button uses the following code to grab the information from that specific row and uses the Fragment to edit the entry.
widget.datasource.saveChanges();
app.datasources.SystemOrders.selectKey(widget.datasource.item._key);
app.showDialog(app.pageFragments.SystemOrders_Edit);
The Copy button is currently using the following code to duplicate the entry and automatically create it.
//Allows for copying table/row
var rowDataSource = widget.datasource;
var listDatasource = app.datasources.SystemOrders_HideComplete;
var createDataSource = listDatasource.modes.create;
widget.datasource.saveChanges();
// Enter fields you want to duplicate below
createDataSource.item.ProjectName = rowDataSource.item.ShowName;
createDataSource.item.DeliveryInfo = rowDataSource.item.DeliveryInfo;
createDataSource.item.SOB = rowDataSource.item.SOB;
createDataSource.item.DeliveryDate = rowDataSource.item.DeliveryDate;
createDataSource.item.Company = rowDataSource.item.Company;
createDataSource.item.Location = rowDataSource.item.Location;
createDataSource.item.AdditionalPeripherals = rowDataSource.item.AdditionalPeripherals;
createDataSource.item.Notes = rowDataSource.item.Notes;
createDataSource.createItem();
I would like to change this behavior so that the Copy button grab the values from those specific fields, however instead of doing a createDataSource/createItem(); I want it to place those values into a Page Fragment (ex: SystemOrders_Add) that has the corresponding fields.
This way the user can click "Copy" and the SystemOrders_Add Fragment appears with pre-populated values.
I want to make sure these values are only in the Page Fragment and do not get commited until the user presses the Submit button.
newSOEmailMessage(widget);
widget.datasource.createItem();
app.closeDialog();
Thank you for your help!
one way you can accomplish this is by passing the data to Custom Properties defined in your Page Fragment and then you can place those properties to the corresponding fields. I recommend you also check this article https://developers.google.com/appmaker/ui/viewfragments#use_custom_properties_to_customize_page_fragments
First you need to create the Custom Properties inside your Page Fragment. Then in your Copy button onClick event you can use something like this to save the row data from your table to the Custom Properties:
var rowDataSource = widget.datasource.item._key;
app.datasources.SystemOrders.selectKey(rowDataSource);
var projectName = app.datasources.SystemOrders.item.project_name;
var deliveryInfo = app.datasources.SystemOrders.item.delivery_info;
//...
app.pageFragments.SystemOrders_Edit.properties.ProjectName = projectName;
app.pageFragments.SystemOrders_Edit.properties.DeliveryInfo = deliveryInfo;
//...
app.showDialog(app.pageFragments.SystemOrders_Edit);
Assuming you have a form inside your Page Fragment, you can bind the value of each field with custom properties. Binding will ensure that the data is pre-populated. This can be done for each field via the Property Editor and the binding should look like this: #properties.ProjectName
Inside your Submit button onClick event you can use something like this to create a new item in the datasource using the values available in each field.
var projectName = widget.root.descendants.Field1.value;
var deliveryInfo = widget.root.descendants.Field2.value;
//...
var myDatasource = app.datasources.SystemOrders_HideComplete;
var myCreateDatasource = myDatasource.modes.create;
var draft = myDatasource.modes.create.item;
draft.project_name = projectName;
draft.delivery_info = deliveryInfo;
//...
// Create the new item
myCreateDatasource.createItem();
app.closeDialog();
You can set properties back to null once item is created (maybe onDetach) like this:
app.pageFragments.SystemOrders_Edit.properties.ProjectName = null;
Hope this helps!
I have a feeling that removing this line from the Copy Button click handler will make a trick(of course, if your page fragment is bound to ds.modes.create.item):
createDataSource.createItem();
In case, you are using Manual save mode and you are trying to reuse Page Fragment without overriding datasource... you need create new items using different approach:
// Copy Button click handler
var source = widget.datasource.item;
var listDatasource = app.datasources.SystemOrders_HideComplete;
// This line will add new item to the list datasource
// without saving it to database.
listDatasource.createItem();
var target = listDatasource.item;
// Enter fields you want to duplicate below
target.Field1 = source.Field1;
target.Field2 = source.Field1;
...
// Show fragment (assuming it is bound to listDatasource.item)
app.showDialog(app.pageFragments.EditItemFragment);
// -----------
// Page Fragment's Submit Button click handler
...
listDatasource.saveChanges(function() {
// TODO: handle successful save
});
Thank you to Pavel and Wilmar. The solution that worked for me is listed below:
//Allows for copying table/row
var rowDataSource = widget.datasource;
var listDatasource = app.datasources.SystemOrders_HideComplete;
var createDataSource = listDatasource.modes.create;
widget.datasource.saveChanges();
// Enter fields you want to duplicate below
createDataSource.item.ShowName = rowDataSource.item.ShowName;
createDataSource.item.DeliveryInfo = rowDataSource.item.DeliveryInfo;
createDataSource.item.SOB = rowDataSource.item.SOB;
createDataSource.item.Notes = rowDataSource.item.Notes;
app.datasources.SystemOrders.selectKey(widget.datasource.item._key);
app.showDialog(app.pageFragments.SystemOrders_Add);
I have the following code in the init() of a report:
QueryBuildDataSource qbdsTable;
QueryOrderByField QueryOrderByFieldTransDate;
QueryOrderByField QueryOrderByFieldDimZone
QueryOrderByField QueryOrderByFieldDimCC;
;
super();
qbdsTable = query.dataSourceTable(tableNum(Table));
QueryOrderByFieldTransDate = qbdsTable.addOrderByField(fieldNum(Table, TransDate));
QueryOrderByFieldTransDate.autoSum(true);
QueryOrderByFieldDimZone = qbdsTable.addOrderByField(fieldNum(Table, DimZone),SortOrder::Descending);
QueryOrderByFieldDimZone.autoSum(true);
QueryOrderByFieldDimCC = qbdsTable.addOrderByField(fieldNum(Table, DimCostCenter));
QueryOrderByFieldDimCC.autoSum(true);
and the autosum property is functioning properly (I have set the SumAll property for the field I use to calculate these subtotals).
The problem is that, whenever I try to add an groupBy field or a selection field, the autosum property isn't honored anymore (the subtotals are not displayed anymore):
qbdsTable.addSelectionField(fieldNum(Table, AmountMST), selectionField::Sum);
or
qbdsTable.addGroupByField(fieldNum(Table, TransDate));
I have tried to use:
qbdsTable.addSortField(fieldNum(Table, TransDate));
qbdsTable.autoHeader(1, true);
but I have the same problem
Does anyone has an Idea how I can use both autosum and addGroupByField on the same datasorce of a report?
For historical reasons old style AX reports behaves differently when called directly (run on the report node) or through on a report menu item.
The execution order of the first is:
init
fetch
dialog
The second runs via class RunbaseReportStd in the following order:
init
dialog
fetch
This matters because you have change the query after the user has made any changes.
So move your code changes from init to fetch, like this:
public boolean fetch()
{
QueryBuildDataSource qbdsCustTrans = query.dataSourceTable(tableNum(CustTrans));
;
qbdsCustTrans.addSelectionField(fieldNum(CustTrans, AmountMST), selectionField::Sum);
qbdsCustTrans.addGroupByField(fieldNum(CustTrans, AccountNum));
qbdsCustTrans.addGroupByField(fieldNum(CustTrans, TransDate));
qbdsCustTrans.addGroupByField(fieldNum(CustTrans, CurrencyCode));
//info(qbdsCustTrans.toString());
return super();
}
This will only work, if called through the menu item.
Also, I could not get the auto-sum functionality to work, when added by code.
Instead you will have to add the order by and autosum using Sorting node of the report query.
I don't know why, but maybe this is because you use auto design, which is generated at run time.
I have an Movie Clip in Flash that have subobject of button type which has subobject of input text and movie clips. Right after creation core Moveclip all subobject are set to null, when I expect them to be valid objects.
// hierarchy:
// core:MC_Core_design
// button_1:B_Mybutton
// text_name // dynamic text with instance name
// mc_icon // movie clip with instance name
var core:MC_Core_design = new MC_Core_design();
addChild(core);
core.button_1.text_name.text = "hello world"; // error: text_name is null
core.button_1.mc_icon.visible = false; // error: mc_icon is null
MC_Core_design was created in Flash and exported to Actionscript. I've done this for button_1 class aswell. The code was written using Flex.
When I comment out both lines that result in error I get correct view of the core Movie clip with all subobject.
How can I set subobject properties right after object creation?
You need to listen for the Event.INIT from the class when it is created. (If you are not embedding a symbol using the Embed metatag then Flash takes a few milliseconds to initialize the loaded movieclip). This does not seem to be a problem if the Flash IDE swf/swc does not contain any actionscript)
The issue is sometimes it can be really quick, so it fires the INIT event before you get a chance to attach the event listener to the object. so you can't just attach it after you instantiate the object.
A work around is to embed the swf as a byte array, then use the loader class to load the embedded bytes (This lets you set the event listener before calling load).
e.g.
[Embed(source="assets.swf", mimeType="application/octet-stream")]
private var assetBytes:Class;
private var clip:MovieClip;
private var loader:Loader;
public function LoadBytesExample()
{
loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.INIT, onAssetLoaded);
loader.loadBytes(new assetBytes());
}
private function onAssetLoaded(e:Event):void
{
var loader:Loader = (e.currentTarget as LoaderInfo).loader;
(e.currentTarget as LoaderInfo).removeEventListener(Event.INIT, onAssetLoaded);
clip = loader.content as MovieClip;
this.addChild(clip);
clip.someTextField.text = "HELLO WORLD";
}
Sorry for the formatting, just wrote that off the top of my head
And the syntax for embedding the symbol (You won't need to load this via a loader as the actionscript in the external swf/swc is stripped).
[Embed(source="assets.swf", symbol="somesymbol")]
private var assetSymbol:Class;
private var clip:MovieClip;
public function LoadSymbolExample()
{
clip = new assetSymbol();
clip.sometext.text = "Hello World";
}
If I see it right, button_1:B_Mybutton is not yet initialized.
I mean something like : button_1:B_Mybutton = new B_Mybutton();
About the other two variables text_name & mc_icon as you describe if they have been initialized already (as you term them as instance names), Iguess they should not give you any problem.
Also I asssume that you are setting access modifiers to all as public.
If you still have problem... pls share how all the required variables are defined. Just the relevant part would be enough.
