Only first TreeView.reveal works

[weinand]

Testing #44364:

My reveal command just calls the TreeView.reveal:

  processViewer.reveal(newItem);

• If I run this command for the first time, it works fine and it opens a collapsed node to show its child.
• then I collapse the parent node again
• If I now use the command a second time, the item is not revealed but I see this error:
  

This problem prevented me from using "reveal" in code that detects model additions and tried to reveal the newly created items.

@weinand Can I try to reproduce this using your processes extension?

The error means that the system does not have the node with id 1/27493. Can you check if you are returning this element when getChildren method on your data provider is called?
