    dragValue is null when drag and drop in two different forms

    geoffrey lalloue Newbie

      hi,

      i have tried to make a drag and drop between two different forms, but the drag value in the droplistener is always null in the second one.

      (when i try it in the same form, everything is good).

       

      i know that there was some troubles with the drag and drop in twho different forms but i think it's fixed.

       

      please, help me

       

      Thanks ain advance.
