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
reference.
at mx.managers::SystemManager/get
toolTipChildren()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\managers\SystemManager.as:1178]
at
mx.charts.chartClasses::ChartBase/updateDataTipToMatchHitSet()[C:\work\flex\dmv_automation\projects\datavisualisation\src\mx\charts\chartClasses\ChartBase.as:3030]
Does anyone have any clue what is going on?????? Thanks,
Jim
!!!!!!!!!! snippet where swf is loaded !!!!!!!!!!!!

!!!!!!!!!! snippet when adding to Canvas !!!!!!!!!!!!
if (event.moduleApp != null)

starting the RL context for :" + moduleId);
// Make sure the content fills the page
var subAppComponent:SubAppBase =

/* Add to contentViewStack here based upon

exists for the module
*/
var index:int = _moduleArray.getItemIndex(swf);
var canvas:Canvas =
Canvas(contentViewStack.getChildAt(index));
canvas.addChild(subAppComponent);
}
