Let's say I have a list and a button. An element of this list can be selected (only one at a time). If an element is selected, the button will do changes A, if not, it will do changes B.
My question is, should I have the button fire ACTION_BUTTON_CLICKED and the reducer can figure out if it's supposed to do A or B based on it's current state (isElementSelected) or should the button decide which action to fire, ACTION_A or ACTION_B?
Obs.: they button will have it's text as Button(A) or Button(B) based on whether an element is selected or not.

Using Adobe Captivate 9. I have a text box which changes states to show different info on a single slide.
On the slide there is a forward and back button which changes the state of the text box. When clicking the next button on the last state it goes back to the first state. Is there a way to prevent this? Or hide the next button when on the final state.
You can build an advanced action to control moving through the state. First creat a variable that equals 0. Second create an advanced action that adds 1 to the variable each time you click the the next button to move through the state (-1 for the previous button). On a new tab in the advanced action, create a conditional action (if variable = number of clicks to get to last state, then hide button). Do the same for the previous button (if variable = 0, then hide previous button). You will also want one to show the buttons (if variable is not equal to 0, then show previous button) and (if variable is not equal to number of clicks, then show next button).
The case:
I have Activities as datamodel.
I have set Activities to have many-to-many relationship with themselves to represent a Parent / Child relationship.
I have set up an accordion widget. Each row of the accordion contain basic data about the Activity record + some buttons.
I have set one of the button's onClick functions to open a popup, which allows me to edit the Activity detail in a form.
When I click a different record from the same accordion, the form from the popup reflects the data in the selected record.
The problem:
I have nested accordions which represent the "Child" Activities of the Parent Activity.
I have also added a similar button, which opens a popup. I can open the popup, which targets the child records, but cannot make it open the specific record, from which I pressed the button.
So the popup open by default on the first child.
Please help - how can I make the popup change naturally to reflect the datasource / selected record of even nested datasources?
What I tried:
In order to try and make to popup work I have tried to set the datasource based on the relationship:
Activities: Sub_Activities(relation)
This works to the extent of showing the related items, but popup content does not dynamically change on clicking a different child record or clicking the button from a different child record.
In both cases what is shown is the first child record.
What I understand is that you have a set up in which you click a button and a popup shows. The popup should let you view/edit the record referenced in the row where the button is. If that is the case, then probably you already have almost everything setup for the next thing to work. First, add a string custom property to the popup and name it selectedKey. Then, on the onClick event of the button that opens the popup, add something like this:
var key = widget.datasource.item._key;
app.popups.MYPOPUP.properties.selectedKey = key;
app.popups.MYPOPUP.visible = true;
Now, go to the popup content and add the following on the onAttach event handler:
var key = widget.root.properties.selectedKey;
widget.datasource.selectKey(key);
This is the general idea of how to make it work; However, in order for it to work, your datsources in the widgets should be properly set up. Good luck!
Preamble
I have uneditable combobox (user can select from list, but can't type). I suppose, when user have focus on it and press DELETE, it's selection must be cleared? It seems that it is (screenshot was made when I selected some value and then pressed DELETE):
selectionModel is null - screenshot
Problem
But UI control still shows old value, it wasn't cleared. Also ValueChanged listener wasn't triggered.
How to cause
Create ComboBox and fill it with some values. Select any value. You already have selection on it, but it's not enough - now DELETE pressing won't even clear selectionModel. The same with selecting by TAB. Select it with double click (expand and collapse) and then press DELETE. Now selectionModel must be cleared, but UI still show your value.
Another thing: if you closed ComboBox, pressing DELETE will trigger ValueChanged listener. Pressing DELETE on expanded ComboBox won't trigger it, but nevertheless value will become null.
Did anybody face with this? Any ideas to make it work naturally i.e. clear selectionModel and update UI?
Well, the problem was not exactly where I thought. "Delete" button did nothing in any case, ComboBox was cleared because it's items list was refreshed every time when it was expanded -> old items were deleted including selected. Problem was the same - UI wasn't updated. So I resolved this by adding ComboBox.getEditor().clear() before refreshing it's items list in onShowing event.
I have a list of items with Actions drop-down for each item in the left-section of page. I also have a right rail which displays a different component based on action type selected. I'm using aux-route to accomplish this.
One of the Action the user can take is "edit" where in a form is displayed to edit the metadata of the list item. While editing, user can click on + button next to some of the input field to add another input field dynamically.
Now my problem is, when the edit-form is open for a list item and I click edit on another item in the list, I wanted my edit-component to be re-instantiated.
Because the aux-route is same for all the list items for edit-action, edit-view is not instantiated once again. Is there a way to achieve it?
Right now fixed it with RouteReuseStrategy
I'm used to using boolean bindings with IBM buttons to track if a button is clicked. The button in Brazos UI can be bound to any variable type but doesn't make automatic updates to booleans. How do I use bindings with Brazos UI buttons to track which was last-clicked?
The binding of a button is really only useful in tables. The acceptance of ANY variable type for the binding of a button stems from the use of determining the index of a selected row or obtaining the entire row object:
If you bind and integer to the button in a table, the binding will update with the index of the row when the button is clicked.
If you bind a variable of the same (singular) type as the table's binding, then clicking the button will update the binding with that row's data.
Both of those are handy interactions with the table control but don't work for tracking which button is clicked when used elsewhere on a coach. For that, you want to utilize the 'Button Control ID' configuration option. The most direct method is to bind the same string variable to all of the buttons you need to track. When clicked, a button will update that shared variable to match its own control ID. You can then use that unique ID in various scripting checks to take button-specific actions.
