Subject Getting an IndexOutOfBoundsException with tomahawk tree component
Date Tue, 15 Aug 2006 10:40:02 GMT

Hi,

I have tried asking this question on the users list but no one is replying.
Sorry if I have made a mistake trying this list but I am stuck.

Using myfaces and tomahawk both 1.1.5 snapshot. In Webspere 5.1 test
environment.

I am receiving the IndexOutOfBoundsException when I try to change my tree
model while my tree is expanded.
I think it is when the model is shorter than the number of nodes expanded on
the page.

Not sure if this is a bug or there is a way of collapsing the tree before
changing the model.

My page is shown below.
When the user clicks the OK command button then the tree model changes based
on the selectOneMenu.
