Matt Hughes updated FLEX-33329:
-------------------------------
Attachment: remove_focus_manager.png
I can break the one link to the focusManager by setting the focusManager.form =
null, but there are still other references.
In the popup, I added this code to get this revised memory snapshot:
private function okButton_clickHandler(event:MouseEvent):void
{
dispatchEvent(new CloseEvent(CloseEvent.CLOSE));
focusManager.mx_internal::form = null;
}
> Popup with TextInput never garbage collected
> --------------------------------------------
>
> Key: FLEX-33329
> URL: https://issues.apache.org/jira/browse/FLEX-33329
> Project: Apache Flex
> Issue Type: Bug
> Components: Focus Manager, PopUp Manager, Spark: TextInput
> Affects Versions: Apache Flex 4.8 (parity release)
> Reporter: Matt Hughes
> Attachments: memory_snapshot.png, ProfilingTest.mxml,
> remove_focus_manager.png, TitleWindowWithText.mxml
>
>
> In the attached sample application, we use a button to create a popup. That
> popup has a TextInput and a Button. If you enter text in the text input and
> click the button, we close the popup.
> If you take a memory snapshot after the popup has been closed, it still
> remains in memory. If you go through this cycle again and create another
> popup and close it, it keeps acrueing instances.
> If you don't focus into the text input, you don't get the memory leak.
> This was documented before here
> (https://issues.apache.org/jira/browse/FLEX-20312) but the issue is still
> reproducible in 4.8 and I don't know of any workarounds.
