Hello,
There is a bug in filtering by more than dropDown in treeGrid.
When I filtered by any item in the dropDown for column (Status) and then by the first item in the dropDown for column (Piriority), the data didn't affected and by debugging, the actionBegin event hasn't been called.
I faced this problem and by multiple-case testing, I've found that the problem occurs always if I filtered by any item in a dropdown and then by the first item of another dropdown.
Kindly find the attached file for my example and for the screenshot.
