TreeGrid setExpandOnFilter(false) after filtering don't open leafs

[peterarsentev]

Hello I have a strange behavior in TreeGrid when I set setExpandOnFilter(false). It does not open leafs after filtering.
I made a maven project where you can testing it.
http://www.2shared.com/file/sP9XAVt2/TreeMX.html

How to repeat bug.
1. unpack
2. go to TreeMX
3. mvn gwt:run
4. inter 0 in filters field
5. try to open node after filtering.

Please check it and fix it.

Regard.

Can you please post just the required EntryPoint class as plain text here?

The testcase should just be a single class implementing EntryPoint.

Yes sure
