I'm using JSF1.2 apache trinidad tag. I have a requirement like based on the drop down list the associated list of array values should get rendered into the UI.My Bean will have a map (drop down value as key which is unique, the associated list of values retrieved from DB) will be readily available when the page loads. In java script, how to retrieve the associated list value from this map and how to return back the array value into UI? Is there any other options available to achieve this requirement?
Your help on this is really much appreciated.
If I understand this right, you have the entire map available when the page is rendered.
You could prebuild the selectItems in the dropdown beforehand like this:
Map<String, List<String>> map;
//read the map content here
List<SelectItem> items = new ArrayList<SelectItem>();
for(String key: map.keySet()){
items.add(new SelectItem(key, map.get(key)));
}
These items will have the key as the label and the corresponding array as the value.
When you use this in your interface you can do this:
<tr:selectOneChoice value="#{bean.selectedArray}" required="true" autoSubmit="true">
<f:selectItems value="#{bean.items}"
</tr:selectOneChoice>
<tr:outputText value="#{bean.selectedArray}" />
The code isn't complete, but it should get you started.

See Datasource Paging Issue (Revised)
for the original question.
Markus, you were kind enough to help with out with the issue of incorporating a record count into a query using a calculated datasource. I have a search form with 15 widgets - a mix of date ranges, dropdowns, text values and ._contains, ._equals, ._greaterThanOrEquals, ._lessThanOrEquals, etc.
I have tested this extensively against mySQL SQL code and it works fine.
I have now added a 16th parameter PropertyNames, which is a list with binding #datasource.query.filters.Property.PropertyName._in and Options blank. The widget on the form is hidden because it is only used for additional filtering.
Logic such as the following is used, such that a particular logged-in user can only view their own properties. So if they perform a search and the Property is not specified we do:-
if (params.param_Property === null && canViewAllRecords === false) {
console.log(params.param_PropertyNames); // correct output
ds.filters.Property.PropertyName._in = params.param_PropertyNames;
}
The record count (records.length) is correct, and if I for loop through the array of records the record set is correct.
However, on the results page the table displays a larger resultset which omits the PropertyNames filter. So if I was to search on Status 'Open' (mySQL results 50) and then I add a single value ['Property Name London SW45'] for params.param_PropertyNames the record count is 6, the records array is 6 but the datasource display is 50. So the datasource is not filtering on the property array.
Initially I tried without adding the additional parameter and form widget and just using code such as
if (params.param_Property === null && canViewAllRecords === false) {
console.log(params.param_PropertyNames); // correct output
ds.filters.Property.PropertyName._in = properties; // an array of
properties to filter out
}
But this didn't work, hence the idea of adding a form widget and an additional parameter to the calculated recordcount datasource.
If I inspect at query.parameters then I see:-
"param_Status": "Open",
"param_PropertyNames": ["Property Name London SW45"],
If I inspect query.filters:-
name=param_Status, value=Open
name=param_PropertyNames, value=[]}]}
It looks as though the filter isn't set. Even hard coding
ds.filters.Property.PropertyName._in = ['Property Name London SW45'],
I get the same reuslt.
Have you got any idea what would be causing this issue and what I can do for a workaround ?
Using a server side solution I would suggest editing both your SQL datasource query script (server side) that is supposed to filter by this property list and including the same code in your server side script for your calculated Count datasource. The code would look something like this, not knowing your exact details:
var subquery = app.models.Directory.newQuery();
subquery.filters.PrimaryEmail._equals = Session.getActiveUser().getEmail();
subquery.prefetch.Property._add();
var results = subquery.run();
if(!results[0].CanViewAllRecords) {
query.filters.Property.PropertyName._in = results[0].Property.map(function(i) {return i.PropertyName;});
}
By adding this code you are filtering your directory by your current user and prefetching the Property relation table, then you set the filter only if your user canviewallRecords is false and use JS map function to create an array of the PropertyName field in the Property table. As I stated, your code may not be exactly the same depending on how you have to retrieve your user canviewallrecords property and then of course I don't know your relation between user and Property table either, is it one-to-many or other. But this should give you an idea how to implement this on server side.
I'm writing a GUI extension and using the Anquilla framework to get a list of Keywords within a Category. I'm obtaining an XML document for the list of keywords then working with that document within my extension.
My problem is that the returned XML doesn't contain the Keyword's 'Description' value. I have the Title and Key etc.
My original code looks like this:
var category = $models.getItem("CATEGORYTCMID:);
var list = category.getListKeywords();
list.getXml();
A typical node returned is this:
<tcm:Item ID="tcm:4-1749-1024"
Type="1024" Title="rate_one" Lock="0" IsRoot="true"
Modified="2012-12-17T23:01:59" FromPub="010 Schema"
Key="rate_one_value" IsAbstract="false"
CategoryTitle="TagSelector"
CategoryID="tcm:4-469-512" Icon="T1024L0P0"
Allow="268560384" Deny="96" IsNew="false"
Managed="1024"/></tcm:ListKeywords>
So I've tried using a Filter to give me additional column information:
var filter = new Tridion.ContentManager.ListFilter();
filter.columns = Tridion.Constants.ColumnFilter.EXTENDED;
var list = category.getListKeywords(filter);
Unfortunately this only gives the additional XML attributes:
IsShared="true" IsLocalized="false"
I'd really like the description value to be part of this XML without having to create a Keyword object from the XML. Is such a thing possible?
cough any ideas? cough
I'm afraid you'll have to load the Keyword itself to get the Description.
It's not used in any lists, so it's not returned in the XML.
You could always create a List Extender to add this information to the list, but try to be smart about it since this extender will execute everytime a GetList is called.
Won't save you from having to open every keyword in the list, but you'll be doing it server-side (with Core Service/NetTcp for instance) which will probably be easier and faster than opening each keyword with Anguilla.
In this instance I only need the one keyword, so I simply get it from the CMS. Getting an object in Anguilla is a bit weird, here's the code:
In your main code area:
var selectedKy = $models.getItem("TcmUriOfKeywordHere");
if (selectedKy.isLoaded()) {
p.selectedKy = selectedKy;
this.onselectedKyLoaded();
} else {
$evt.addEventHandler(selectedKy, "load", this.onselectedKyLoaded);
selectedKy.load();
}
It's worth noting how I store the keyword in the properties of the item, so I can obtain it in the onselectedKyLoaded function
The function called once the item is loaded
ContentBloom.ExampleGuiExtension.prototype.onselectedKyLoaded = function (event) {
var p = this.properties;
var selectedDescription = p.selectedKy.getDescription();
// do what you need to do with the description :)
};
I resolved this, thanks to the answer here: https://stackoverflow.com/a/12805939/1221032 - Cheers Nuno :)
I implemented a ribbon tool bar button for Tridion 2011 SP1, which opens an aspx page and populates a drop down list based on a look-up component. The look-up component comprises of different embedded schemas. To filter out the values based on embedded schema name I need to get the Embedded schema field values of component creation page on button click in button JavaScript.
Because in my component creation page consists of multivalued Embedded schema field has the info, which helps look up value filtering process. I am unaware of the command need to be used for the requirement. I know about a command to get the complete component XML, that is: $display.getView().getItemFields().
To get the present RTF field content I am going for the command: target.editor.getHTML(). To get the complete set of Embedded schema field values only,
which command I need to use?
My sample component source:
<root>
<a>sample a</a>
<b>sample b</b>
<c>
<ca>ca 1</ca>
<cb>cb 1</cb>
<cc>cc 1</cc>
</c>
<c>
<ca>ca 2</ca>
<cb>cb 2</cb>
<cc>cc 2</cc>
</c>
<c>
<ca>ca 1</ca>
<cb>cb 1</cb>
<cc>cc 1</cc>
</c>
</root>
I don't think there are public API for that. But you could use component data xml and then parse it by yourself:
var item = $display.getItem();
var xml = item.getContent(); // OR $display.getView().getItemFields();
var xmlDoc = $xml.getNewXmlDocument(xml);
var schema = item.getSchema();
if(schema.isLoaded())
{
var xpath = "/custom:{0}/custom:embeddedFieldName".format(schema.getRootElementName());
var fields = $xml.selectNodes(xmlDoc, xpath, { custom: schema.getNamespaceUri() });
// loop fields and get values ...
}
I am working on the Event Handler for saving a component.
My objective is to perform some validations when the user creates and component based on a schema.
I have a schema with the name "Employee".
Employee has an embedded schema with the name "Experience" and it is multivalued.
Experience has 3 fields.
Role : Drop down with the values Manager, Lead.
Company: Text field
Years: Text field
When the user enters some data in these fields, I want to do some validations before save.
The high level design would look like this.
Load the instance of the Component
Navigate to embedded field "Experience"
For every "Experience". I need to get the value of the "Role", and check that appropriate value is entered in other two fields(By writing Component Save event)
For( all the repeated "Experience")
{
If (Role=="Manager")
check the values in the other two fields and do some validation
If (Role=="Lead")
check the values in the other two fields and do some validation
}
I am stuck at extracting the value and Names of subfields at the embeddded field.
I have tried:
Tridion.ContentManager.Session mySession = sourcecomp.Session;
Schema schema= sourcecomp.Schema;
if(schema.Title.Equals("Employee"))
{
var compFields = new ItemFields(sourcecomp.Content, sourcecomp.Schema);
var embeddefield = (EmbeddedSchemaField)compFields["Experience"];
var embeddedfields = (IList<EmbeddedSchemaField>)embeddefield.Values;
foreach(var a in embeddedfields)
{
if(a.Name.Equals("Role"))
{
string value=a.Value.ToString();
}
}
}
Actually I am stuck how to retrieve the values in the other fields at the same time.
Can any one explain how it can be done?
What you need to understand on a EmbeddedSchemaField class is that it represents both a schema and a field (as the name implies...)
I always find it helpful to look at the source XML of the component when writing code that targets its fields, you get a good visual representation of what your classes must do. If you look at a component XML like this:
<Content>
<Title>Some Title</Title>
<Body>
<ParagraphTitle>Title 1</ParagraphTitle>
<ParagraphContent>Some Content</ParagraphContent>
</Body>
<Body>
<ParagraphTitle>Title 2</ParagraphTitle>
<ParagraphContent>Some more Content</ParagraphContent>
</Body>
</Content>
Body is your embedded Schema field, which is multivalued, and contains 2 single-valued fields within it.
Addressing these fields in TOM.NET then:
// The Component
Component c = (Component)engine.GetObject(package.GetByName(Package.ComponentName));
// The collection of fields in this component
ItemFields content = new ItemFields(c.Content, c.Schema);
// The Title field:
TextField contentTitle = (TextField)content["Title"];
// contentTitle.Value = "Some Title"
// Get the Embedded Schema Field "Body"
EmbeddedSchemaField body = (EmbeddedSchemaField)content["Body"];
// body.Value is NOT a field, it's a collection of fields.
// Since this happens to be a multi-valued field, we'll use body.Values
foreach(ItemFields bodyFields in body.Values)
{
SingleLineTextField bodyParagraphTitle = (SingleLineTextField)bodyFields["ParagraphTitle"];
XhtmlField bodyParagraphContent = (XhtmlField) bodyFields["ParagraphContent"];
}
Hope this gets you started.
I have a script that parses some complex XML. When the XML element is of a certain type, it generates a comboBox using the XML element's children to populate the box. I then want to check all of the values of the all the generated ComboBoxes against their correct answers (which is also info stored in the XML file). When creating the ComboBoxes, I added an "id" property. However, it seems that I cannot them use:
dynamicQuestion.id.selectedItem.labelField
to check the answers. However, I am able to get the labelField if I know the variable name used to create the ComboBox.
dynamicQuestion.selectedItem.labelField
This indicates (to me) that I need to dynamically generate the variable name as I'm creating new instances of the ComboBox. But how do I dynamically generate a variable name? If I use
var thisBox:String = "box"+boxCount;
var newBox:ComboBox = thisBox as ComboBox;
I get an implicit coercion error. I also tried changing the creation statement to a function that accepted an argument, "thisBox," but this didn't work either. Conceptually, this seems quite simple, but I'm having a hard time putting it to practice. It seems that the comboBox's id is what is generated by created the box using script (e.g., var thisBox). How do I dynamically generate this name?
Use an array as Stefan suggested. If you must use string identifiers, you can create an object and use it as an associative array.
var combos:Object = {};
var boxCount:Number = 1;
var thisBox:String = "box"+boxCount;
//you can store comboboxes in the object using the following syntax
combos[thisBox] = new ComboBox();
//or
combos.box2 = new ComboBox();
//or
combos["box3"] = new ComboBox();
trace(combos.box1.selectedItem.labelField);
trace(combos.box2.selectedItem.labelField);
trace(combos.box3.selectedItem.labelField);
Why don't you store all your dynamically created combo boxes in an array? When you want to evaluate them you iterate over the array and access selectedItem.labelField.
