Mihai Chira created FLEX-34229:
----------------------------------
Summary: DataGridEditor doesn't remove the Event.DEACTIVATE
listener on destroyItemEditor()
Key: FLEX-34229
URL: https://issues.apache.org/jira/browse/FLEX-34229
Project: Apache Flex
Issue Type: Bug
Components: Spark: DataGrid
Affects Versions: Apache Flex 4.12.0
Reporter: Mihai Chira
Priority: Minor
Fix For: Apache Flex 4.13.0
Attachments: _editorDeactivateHandler.fxp
Steps to reproduce:
1. Import and run attached project.
2. Set a breakpoint in DataGridEditor.deactivateHandler().
3. Double click on 'hello' to show the editor.
4. Click in the grid under 'hello' to remove the editor.
5. Click on the Remove Grid button.
6. Click anywhere outside the AIR app to de-focus it.
Actual result: the breakpoint is triggered, which means that the DataGridEditor
is still responding to Event.DEACTIVATE even after the editor was closed, and
even after the grid was removed.
Desired result: DataGridEditor.deactivateHandler() should only be called while
an editor is open, as long as the grid itself is still on stage (NB the grid
can be removed while the editor is still open, see FLEX-34216 for the problems
that causes)
Expected result: the breakpoint is not triggered.
Notes:
-the second line of DataGridEditor.destroyItemEditor() looks like a typo:
instead of addEventListener shouldn't it say removeEventListener(...)?
