Description Kenn Hussey CLA 2011-08-08 14:58:42 EDT 
There is a strange different between the behaviour of the change recorder in the "normal" runtime and the GWT runtime. I've localized the problem to the ChangeRecorder#createListChanges(EList, EList, EList) method. In GWT, it seems that the latter part of the method, i.e., the part after the for (;;) loop, never gets executed. It's as if the GWT compiler can't properly handle the code in that loop for some reason and just drops the remainder of the method when concerting it to Javascript. For some reason, changing the loop to while (true) instead fixes the problem.
