    [ https://issues.apache.org/jira/browse/FLEX-26322?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14126919#comment-14126919 ] 

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..
