Strange exception while using TreeViewAdv

[Jakub]

Hello!

I have an application which have few collections of pages. Each page is an Canvas with controls on it. On one of this pages i have treeViewAdv control.

I load this page and everything is ok, then i have function to close current colletion of pages and return to home screen with every collection of pages. During this process i am clering every object of currnt collection of pages.

I am loading this collection once again and when i move to page with TreeViewAdv i get null reference exception but I don't know what is null - stack trace is in attacked file
