----------------------------------------

Check out the latest SVN code.  I added the message stuff as planned.  Please test and verify that this works.  I hope to add support for the value binding "hook" shortly.

> If a node gets deleted between the time it is clicked on and when the server processes
> the request I get this error:
>  
>  java.lang.IllegalArgumentException: Node with id 0:1:1. Failed to parse 0:1:1
>  
> Basically the node's child was deleted and the index of the child list is no longer
> valid. It was valid when the tree was displayed. This gets thrown from
> TreeModel.getNodeById() when an IndexOutOfBoundsException is thrown by the child list.
> This should be handled more gracefully, like by adding a faces context message, "The selected item no longer exists.", and the processing of the rest of the tree nodes should continue. The end user can choose whether or not to show the messages.
