asked on Popup Window not executing creationComplete="initApp()"
I have a popup window that only executes creationComplete="initApp(
I need to force "initApp()" to run each time the popup is opened in order to get data via an HTTPService.
Thanks!

here you go:
// FOLLOWING IS THE FILTER POPUP FORM
private var filter : ViewFilters = new ViewFilters;
// USER SELECTED TO VIEW (EDIT) THE CHART FILTERS
private function handleViewFilters() : void {
if (dG1.selectedIndex == -1) return; //user needs to select a chart before viewing Filters
mx.managers.PopUpManager.a
mx.managers.PopUpManager.c
with (filter) {
chartID = dG1.selectedItem.Id;
}
]]>
</mx:Script>

Would the better route be to switch from calling a popup to calling a custom component with a viewstack or state?
Thanks!
Thanks!
Explanation:
Calling
>> mx.managers.PopUpManager.r
makes your filter disappear, but doesn't "delete" it.
Next time you call
>> mx.managers.PopUpManager.a
**the same filter** is shown again.
By calling resetFilter() after PopUpManager.removePopUp(f
you are assured that the next time you do
>> mx.managers.PopUpManager.a
a NEWLY CREATED filter is shown

In my opinion that popup is OK. As long as you make sure - e.g. by using the code I posted - its content is up-to-date

I got the syntax wrong because I get "undefined method resetFilter" error.
private function handleCancel() : void {
mx.managers.PopUpManager.r
resetFilter();
}
Sorry, I am new to Flex.
private function handleCancel() : void {
mx.managers.PopUpManager.r
resetFilter();
}

Ok, I am still having the error in the viewFilters.mxml - "call to possibly undefined method resetFilter".
Does the following belong in the ChartDesigner.mxml (where the popup is called from) or in the viewFilters.mxml (the popup itself)?

return _filter;

I had to move some things around until I found what when where. But this was the solution and it works great
Thanx 4 axxepting
That's because the popup panel is not recreated. It is simply removed by the popup manager but it still exists invisibly.
When it pops up again it is NOT recreated and hence the creationComplete event is not thrown.
Show me your code where you make the panel pop up.
