Alright, I have a Tree component that’s bound to an array of value objects . I call a function that removes an array item. For some reason, the Tree component doesn’t get updated. So, I force an update by calling invalidateList(). Now, the item disappears from the tree. Everything seems fine. Unfortunately, at this point, when I attempt to select any item on the tree, the program freezes. A while later, I receive this message:

If anyone knows the solution, I’d really appreciate it. Thank you very much. I look forward to a reply.
