Re: [flexcoders] Re: Strange Behavior When Loading Sub Application
Flex SWFs must be on-stage in order to load. Are you worried about missing an
ADD_TO_STAGE event? Maybe send a fake one on applicationComplete.

Your suggestion will work and in fact, that is the way we were doing it.
Unfortunately, we needed to create a Robotlegs context so that we can listen
for ADD_TO_STAGE events and allow it to automatically mediator our view
components (see below). That is why I added the sub-app as a child later. Any
other ideas how to make the current code work?
// Inject dependencies into the module and initiate the context since autoload
is set
var subApp:IModule = event.moduleApp;

Simply add as a child to the stub canvas that already

var index:int = _moduleArray.getItemIndex(swf);
var canvas:Canvas = Canvas(contentViewStack.getChildAt(index));
canvas.addChild(subAppComponent);

Hi,
I am experiencing an odd problem and I hope someone knows why. I am loading
a sub-application using SWFLoader. I listen for the Event.COMPLETE command.
Once the swf is loaded, I then add a listener to the SystemManager for the
swf and listen for the FlexEvent.APPLICATION_COMPLETE event. At that point,
I add the application as a child to a Canvas that exists in a view stack (see
code below). This is great, the content loads, but it doesn't seem to load
correctly. The legends in my charts are not oriented the way they should be
and whenever I roll over an item with a tooltip, I get errors like the
following error:
TypeError: Error #1009: Cannot access a property or method of a null object

Re: [flexcoders] Re: Strange Behavior When Loading Sub Application
Thinking about this a bit more, every child of the sub-swf except its
systemmanager should get an ADD_TO_STAGE around the time of applicationComplete
in the sub-swf. Flex builds the SWF’s ui off-stage. So maybe there’s
something else going on.

Robotlegs uses the ADD_TO_STAGE to auto-magically mediate view components so
dispatching 1 event would not work...I would have to dispatch 1 for each
component. I can manually mediate the components, but that is a lot of work
for a large app and takes the magic away from RL. I will just have to pursue
another strategy. Thanks for your confirmation Alex!

If you look at the comboboxheaderrenderer example you'll see that it
always pulls its data from the column so the renderer can be recycled or
recreated. It does not store state within itself

I am trying to implement a checkbox as a headerRenderer:
public class CheckBoxHeaderRenderer extends CheckBox
{
private var _parentGrid:DataGrid = new DataGrid();
public function CheckBoxHeaderRenderer()
{
super();
selected = true;
addEventListener(click, clickHandler);
}
override protected function clickHandler
(event:MouseEvent):void
{
super.clickHandler(event);
parentGrid.dataProvider[0].processorder = 10;
}
public function set parentGrid(value:DataGrid):void
{
_parentGrid = value;
}
public function get parentGrid():DataGrid
{
return _parentGrid;
}
}
That works fine except that when I click on a checkbox it does not
lose it check mark. Commenting out:
parentGrid.dataProvider[0].processorder = 10;
will resore checkbox's behavior. What am I missing?
