I am new to e4 RCP app development. I have a part with close button and i am displaying a table with data inside this part. I want to close the part and reopen it from menu button. Here i am facing a problem: Once i close the part and trying to show it again using "service.showPart(Part, PartState.VISIBLE);" empty part is displayed but its not able to display the Table content and giving "Widget disposed" exception. Please help me how can i handle this situation. I want to close and reopen the part with Table widget inside it.
