Popup Window not executing creationComplete="initApp()"

I have a popup window that only executes creationComplete="initApp()" the first time the popup is called. When the popup is closed and opened again the creationComplete="initApp()" doesn't run again.

I need to force "initApp()" to run each time the popup is opened in order to get data via an HTTPService.

Thanks!

>> When the popup is closed and opened again the creationComplete="initApp()" doesn't run again.
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.

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.addPopUp(filter,this, true);
                  mx.managers.PopUpManager.centerPopUp(filter);
                  with (filter) {
                        chartID                        = dG1.selectedItem.Id;
                        }

Would the better route be to switch from calling a popup to calling a custom component with a viewstack or state?

Thanks!

zzynx

Explanation:
Calling
>> mx.managers.PopUpManager.removePopUp(filter);
makes your filter disappear, but doesn't "delete" it.
Next time you call
>> mx.managers.PopUpManager.addPopUp(filter,this, true);
**the same filter** is shown again.

By calling resetFilter() after PopUpManager.removePopUp(filter);
you are assured that the next time you do
>> mx.managers.PopUpManager.addPopUp(filter, this, true);
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.removePopUp(this);
                  resetFilter();
            }

Sorry, I am new to Flex.

sorry your post #285 just appeared --- I see

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)?

private function get filter():ViewFilters {
 			    if (_filter==null) {
 			    _filter = new ViewFilters();
     			}
     			return _filter;
				}
				
			private function resetFilter():void {
    			_filter = null;
				}

I had to move some things around until I found what when where. But this was the solution and it works great
