Mousedragging not working after updating the array.

[priya gnana]

i have drawn two rectangles.And implemented dragging event for that rectangles.When,double clicked on the rectangle,the size and position
of the rectangle should changes.And its working fine,until this.but again when i tried to implement the mouse dragged event,i'm unable to
dragg it,even after updating the position and size to the array....

You planning to post your code or this is it?

They some debugging by adding some println() statements to the various listener methods to see if they are being called.
