[jira] [Commented] (FLEX-33450) RTE - PopupManager mx.controls.DataGrid

["Bharath (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLEX-33450?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13619410#comment-13619410 ] 

Bharath commented on FLEX-33450:
--------------------------------

Thanks for this hack Alex. We also have a ComboBox in the lower dg and the [preventDefault()] prevents the focus, in some use-cases, to this ComboBox because the target is not equal to getFocus(). I modified the hack to handle the ComboBox as follows and seems to fix the issue  for ComboBox although I haven't tested for other controls. Is there a better way to handle this generically? Your thoughts please..

public function hack(event:DataGridEvent):void
{
if (flash.utils.getQualifiedClassName(getFocus()) == "mx.controls::ComboBox") return;
if (event.target != getFocus())
{
trace("not us");
event.preventDefault();
}
}

> I'm getting a Runtime Exception on Internet Explorer [TypeError: Error #1009: Cannot access a property or method of a null object reference.] when 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.
