Description Stephan Leicht Vogt CLA 2011-09-08 05:56:58 EDT 
Following error occurs every now and then. (About every 3 minutes) Unfortunatly I don't have information, what could be the cause. As soon as I know more I'll try to build a snippet to reproduce this bug. I hope this error messages helps anyway to locate the source of the Problem.

Javascript error occurred:

In order to react fast on the issue we really need a snippet to reproduce it.
Comment 2 Ivan Furnadjiev CLA 2011-09-21 05:12:01 EDT 
Stephan, any additional information/snippet about this problem?
Comment 3 Stephan Leicht Vogt CLA 2011-10-03 04:19:59 EDT 
Sorry Ivan, that I did not write back sooner. 
The issue persists, but unfortunately I can't give you more information. I told our tester to run a screenrecorder while testing, so we can trace back the steps which lead to the exception. I hope, I can then produce a Snippet to reproduce this problem.
Thanks for your patience.

The issue is propably TreeRowContainer.js#_onAsyncTimer. I'll try to fix it.
Comment 5 Tim Buschtoens CLA 2011-10-17 07:22:27 EDT 
Fixed in HEAD by disposing the async timer in TreeRowContainer.js
