we updated our application from 7.0.2 to 7.0.3 and discovered that onTimer-Updated windows stopped working.

I studied the release notes but didn't find anything that could be related to this issue.

I created a small sample on zk-fiddle to show my problem. It works fine with 7.0.2, but only shows up javascript errors with 7.0.3

This happens at least for Firefox on OSX....
