[richfaces-issues] [JBoss JIRA] (RF-12533) UIDataAdaptor throws NPE with disabled PSS (webflow 2.3)

David Rawlings updated RF-12533:
--------------------------------

    Attachment: TreeStructureManager.java


I had the same problem, using webflow 2.3.1, myfaces 2.1.12 and RichFaces 4.3.3.Final.  I'm not sure what the 'correct' fix is, but I've implemented the attached patch (spring faces 2.3.1 TreeStructureManager) that seems to work ok.  I've added comments in the attached source to show where the patch starts/finishes.

I'm no myfaces/webflow/RichFaces expert so use at your own risk...

> When partial state saving is disabled(javax.faces.PARTIAL_STATE_SAVING=false), nullpointer exception is thrown during restore state phase of webflow rendered view that contains UIDataAdaptor component. In other words NPE exception is thrown on every page submit of webflow rendered views that contain components that exted UIDataAdaptor. Please see log attached and sample application.
