8.1-alpha4 TreeGrid expansion

I am using an AbstractHierarchicalDataProvider for my TreeGrid. And calling the expand() method on the TreeGrid seems to have no effect.

Anyone else has problems with the programmatic expand/collapse ?

Are you still experiencing problems with the latest 8.1 pre-releases (e.g. 8.1.0.rc2)? I believe some issues have been fixed, but if you still have problems, please create an issue in
with instructions on how to reproduce the issue.
