Closing Pop Up empties my ArrayCollections

I have a pop up, and it holds like 3 array collections. When the page is first loaded, those array collections display data perfect. When I close it like:

close="PopUpManager.removePopUp(this);"

And then try and reopen the window. All my data is gone, and fields blank. Is it possible to keep the data contained within those ACs, or do I need to repopulate them every time the pop up is opened?

I am using PureMVC, and after I open the pop up, I do a trace, and EACH time I open it, I see the data I am looking for, but it only populates my list the first time, I open it. Every other time it's empty

trace(mx.utils.ObjectUtil.toString(manageColumns.cols));

I've built a sample for you to look at, might help explain or just make things even more confusing!

Its a tad overkill, but in my opinion how PureMVC should be used to seperate everything.

http://www.ff-ant.co.uk/PopUpWindow_PureMVC_Sample/MyApplication.html

right click for 'View Source'

in the src.view.mediators.PopUpMediator you will find the function popUpCreation_Complete. This is where the PopUp window would get its data and load it into the PopUp from the Proxy.

The Proxy could return an ArrayCollection and the PopUp could have a Datagrid instead of a Panel, you could then set the dataProvider to the ArrayCollection. Any way have a look and hopefully will be of some use.

In pureMVC the data shouldn't be so closely coupled to the popUp. The mediator which opens the popUp should load the popUp with the data which it gets from the proxy.

So Notification triggers popUp, then send Notification to load popUp with data. Then it makes no difference when/where/how the popUp is opened.

When I click the button for the pop up it calls my openPopUpWindow which is currently in the ApplicationFacade. I am trying to handle all pop ups. After openPopUpWindow method is finished, where should I tell it to populate the data? Can't do it in the facade.

I tried a onCreationComplete in the view component, but again, only works the first time the window opens.



public static function openPopUpWindow( ComponentClass:Class, MediatorClass:Class ):void
{
	var window:IFlexDisplayObject = PopUpManager.createPopUp( Application.application as Sprite, ComponentClass, true );
	ApplicationFacade.getInstance().registerMediator( new MediatorClass( window ) );
	PopUpManager.centerPopUp( window );	
	//sendNotification(ApplicationFacade.RETRIEVE_COLUMNS);
}
 
public static function closePopUpWindow( window:IFlexDisplayObject, mediatorName:String ):void
{
	PopUpManager.removePopUp( window );
	ApplicationFacade.getInstance().removeMediator( mediatorName );
}

Open in new window

Maybe I need to use an itemRenderer, or makelistData? How would I use something like that?

http://livedocs.adobe.com/flex/3/langref/mx/controls/List.html#makeListData()

<mx:List id="lstColumns" 
    	dataProvider="{cols}" 
    	width="250" 
        labelField="headerText" 
        allowMultipleSelection="true"
        itemClick="_sendEvent(COLUMN_SELECT)"/>   

Open in new window

Thanks. FlexEvent.CREATION_COMPLETE

That is exactly what I was needing. Didn't know about it. Thank you so much for the complete example. You did a couple other things that are better/a lot cleaner too than I do. Good tips!
