Subject [jira] [Updated] (FLEX-33838) TLF ContainerController.mouseDownHandler null object reference
Date Tue, 22 Oct 2013 10:37:43 GMT

     [ https://issues.apache.org/jira/browse/FLEX-33838?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alexander Scheibe updated FLEX-33838:
-------------------------------------

    Description: 
The mouseDown handler of the flashx.textLayout.container.ContainerController may cause a null
object reference error

(here the code with original comments)
{code}
		public function mouseDownHandler(event:MouseEvent):void
		{
			if (interactionManager && !event.isDefaultPrevented())
			{
				interactionManager.mouseDownHandler(event);
				// grab the focus - alternative is to listen to keyevents on the Application
				// is this necessary?
				if (interactionManager.hasSelection()) 
					setFocus();
			}
		}
{code}
The error occurs in the line interactionManager.hasSelection() because interactionManager.mouseDownHandler(event)
may cause the textFlow to become null and therefore the interactionManager can be null in
that line.
