Hey did you managed to solve this problem? - I have exactly the same issue. Even update to newest Data Grid 2 2.14.0 did not solved the problem.
Hi Plamen,
I have also faced this issue,
My solution is that you have to make custom selection/deselection , In the domain model take a boolean attribute , in the data grid 2 off the selection and take a check box(Custom Content) & assign to boolean value then write your logic on the check box selection/deselection.
Hope you like the answer.
