Description Bernd Hufmann CLA 2011-09-13 13:27:27 EDT 
The endless loop happens when trying to paint during switching of experiments when trace doesn't contain control flow resource information.

The paint-method of class TimeStateCtrl of package org.eclipse.linuxtools.tmf.ui.viewers.timeAnalysis.widgets ends up in a endless loop. 

To reproduce:

Keep switching experiments while one experiment doesn't contain control flow and resource information. When it happens, the GUI will freeze. To see if it's actually looping forever in the above while loop, the test needs to be done in debug mode, so that the execution can be stopped.

Fix for bug

A check for _timeDelta == 0 is missing to exit the while(true)-loop. The patch fixes this bug.
