Michel Pitz commented on FLEX-26322:
------------------------------------
Have found another problem on the same Module. But, at this time, without
changing states, only opening a TitleWindow and closing, and repeating these
steps a few times. After this, reseting all objects and lists of the screen,
the error was shown.
Work around: DO NOT instantiate again the lists. Example: myList = new
ArrayCollection();
Just erase the source. Example: myList.source = [].
Haven't tried doing the following: myList.lenght.length = 0. In order to
truncate the data.
Working fine till now..
