Tree doesn't update correctly
-----------------------------
Key: WICKET-2886
URL: https://issues.apache.org/jira/browse/WICKET-2886
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.4.8
Environment: tomcat 6.0.14, win 7
Reporter: Sergey Plevko
When we add a first child to the node this update doesn't appeare in a browser.
If we collapse/expand this the parent node forced we will see changes. All the
rest updates work correctly.
This bug easily can be reproduced with the next pice of code.
