When you specify renderMode tree the itemsProcFunc is executed but the tree ignores the new data.
I have searched for a solution and found a twitter conversation including Georg Ringer.
He says that the tree is getting his own set of items and therefore is not respecting the itemsProcFunc.

So when renderMode tree is used it should either call the itemsProcFunc on it's result set or their should be a config option in treeConfig to set a specific itemsProcFunc for the tree.
