Hi,

Step to replicate:


1. create a grid with groupings.

2. filter the grid until it only has one group shown.

3. click on any row within the group and click another row (this works fine... browser does not hang).

4. filter the grid until it shows two or more groups.

5. click on any row and the browser hangs.


Note that there is no itemclick or itemdblclick event yet on the gridpanel or viewpanel.


When I remove the Grouping Feature, there's no problem when rows are clicked.
