[richfaces-issues] [JBoss JIRA] Commented: (RF-1460) AjaxStateManager: wrong order of states

[Andrey Peristyy (JIRA)]

    [ http://jira.jboss.com/jira/browse/RF-1460?page=comments#action_12389918 ] 
            
Andrey Peristyy commented on RF-1460:
-------------------------------------

The problem in method  AjaxStateManager#restoreStateFromSession line 292:
 
restoredState = (Object[]) logicalStates.get(logicalStates.firstKey());

As described in  Apache Commons Collections documentation this must return state which most recently inserted but it returns first state instead. 

http://commons.apache.org/collections/api-3.2/org/apache/commons/collections/map/AbstractLinkedMap.html#firstKey()

> AjaxStateManager restores states in funny order (not as expected and described in comments)
> The reason most probably that there is a bug in Apache Commons Collections LRUMap implementation 
> ( that is described in https://issues.apache.org/jira/browse/COLLECTIONS-279 )
> The effect of such behavior - command links do not work in dataTable with dataScroller after the page has been changed.
