------------------------------
Summary: RTE - PopupManager mx.controls.DataGrid
Key: FLEX-33450
URL: https://issues.apache.org/jira/browse/FLEX-33450
Project: Apache Flex
Issue Type: Bug
Components: mx: DataGrid, PopUp Manager
Affects Versions: Apache Flex 4.9.0, Adobe Flex SDK 4.5 (Release)
Environment: Internet Explorer 8, Windows 7
Reporter: Bharath
Priority: Blocker
I'm getting a Runtime Exception on Internet Explorer [TypeError: Error #1009:
Cannot access a property or method of a null object reference.] when using
showing DataGrids on a TitleWindow using PopupManager. It works fine on
FireFox. Unfortunately, all our users prefer Internet Explorer.
1) Open a TitleWindow from the main application.Two DataGrids are laid on a
TitleWindow vertically.
2) Click into an editable column on the FIRST DataGrid and type something.
3) Move your mouse to another application (For eg., Outlook).
4) Now click into an editable column on the SECOND DataGrid.
5) The following exception is raised and the screen goes BLACK.
TypeError: Error #1009: Cannot access a property or method of a null object
reference.
