    Data in AdvanceDdataGrid not changed


      Hello all,
      I have really weird problem, I think it's related to datprovider or something similar.


      I have data grid in ac class (as attribute of this class), in the main app, I was import that class and create new instance, and create ArrayCollection according to some parameters(inside the main), after the ArrayCollection been created I assign it to the AdvanceDdataGrid's dataProvider, and everything OK till now.


      but if I'm trying to change the values in the grid, it's back to previous value immediately, it's seems like the data provider doesn't binded to the  ArrayCollection at all, but like I already said I made the assignment to the dataProvider.


      PS - The grid created inside ac class, and the main flow handled in ac code.




      Thanks in advance,

                      gridColz.editable = true ;

                      gridColGroup.children = [gridColx,gridColy,gridColz];

                      grid.groupedColumns = [gridColGroup]

                      grid.editable = "item";

                      grid.dataProvider = arr ;

            I just realize that the problem related to the group column..

              OK, It seems that I manage discussion with myself here, but I found out that if the dataField removed from group column, than it allows you to edit, but then grid dataProvider not detect the arrayCollection structure.


              Thanks again, I'll be glad to get any piece of information.
