[flexcoders] Data binding not displaying anything on subesquent visits to screen

[Paul Steven]

I could really do with some help on this one.

 

I have a screen (State) in my application that displays some custom mxml
components using a repeater. The first time I come to this screen, all the
data appears correctly. However if I navigate away from this screen to
another screen (State), then return to it, all that appears is a scroll bar,
with no custom components appearing.

 

I would appreciate if anyone can take a peek at my code below to try and
identify the problem. Perhaps this is a problem others have experienced?

 

The relevant code is as follows:

 

<mx:State name="ComponentFolderScreen" basedOn="QualificationSummaryScreen">

                <mx:RemoveChild target="{qualificationSummaryScreenDG}"/>


                                                

                <mx:AddChild relativeTo="{vbox1}" position="lastChild">

                <mx:Tile autoLayout="true" width="740" height="230"
id="tile1" borderStyle="none">


 


                <mx:Repeater id="productsRepeater"
dataProvider="{this.category1}" >

 


                                <local:ComFolderItem
mouseOver="CFSMouseOver_Folder(event)" click="CFSClick_Folder(event)"
studentName='{productsRepeater.currentItem.productName + "(" +
productsRepeater.currentItem.productPrice + ")"}'
componentStatus='{productsRepeater.currentItem.componentStatus}' >

 


                </local:ComFolderItem>

 


                </mx:Repeater>


                </mx:Tile>


                </mx:AddChild>

                                                

</mx:State> 

 

 

And here is the code that populates the ArrayCollection that is the
dataprovider

 

var ComponentFolderData:ArrayCollection = new ArrayCollection();

                                                                

ComponentFolderData = _dataManager.returnComponentFolderData(componentCode);

                                                                

var howManyObjects:uint = ComponentFolderData.length;

                                                                

var objectInstance:Object = new Object();

                                                                

category1 = new ArrayCollection();

                                                                

for (var objectIndex:uint = 0; objectIndex < howManyObjects; objectIndex++)
{

 


    objectInstance.productName =
ComponentFolderData.getItemAt(objectIndex).productName;           

    objectInstance.componentStatus =
ComponentFolderData.getItemAt(objectIndex).componentStatus;


 


    category1.addItem(objectInstance);
