Subject [jira] [Commented] (FLEX-26322) invalidIndex error thrown in LinearLayoutVector when AsyncListView.list property is set before lists object length property is initialized
Date Mon, 30 Jun 2014 12:33:25 GMT

    [ https://issues.apache.org/jira/browse/FLEX-26322?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14047613#comment-14047613
] 

Michel Pitz commented on FLEX-26322:
------------------------------------

I've got the same error on my project. Unfortunately, I'm rarely able to reproduce it. I can't
attach the source code here, because it's a big project. However, here follows how to reproduce
the error:
- A Titlewindow that contains a list with itemRenderers. 
- A Module, with two states, that opens the Titlewindow (State1: Itens' list, State2: Item's
Details;
- An action is performed by the itemRenderer button on a item of the list. Then, the titleWindow
is closed.
- Change the Module's state to show the list of itens, and return to the item's details state
again.
- Open the Titlewindow and just close it.

The error is shown sometimes, by reproducing those steps.
