at the first time when I load file into the linktables and clicked on the diagram.
I am using linktables to display my data.
data getting displayed properly.
I tried removing all the listeners from DiagramView still getting same error only at first time .
Don't know from where mouseReleased() event getting fired.
It seems diagramview take some time to initialize events on diagramview. after few seconds it works properly.
is there any solution not to respond any action until the diagramview initialize properly?

thanks.

Yes , you are right.
I am loading that file using SwingWorker thread.
But in such situation what should be the solution because I need to use SwingWorker for process tracking.
