I have created part in application model and unchecked "To be rendered" check for this part. Now i want to open and show this part. I have created OpenPartHandler :

public class OpenPartHandler {
	@Execute
	  public void execute(EPartService partService) {
		MPart part = partService.showPart("part",PartState.VISIBLE);
		part.setVisible(true);
	  }

	  // Technically not needed
	  // will default to true
	  @CanExecute
	  public boolean canExecute() {
	    return true;
	  }
}

Is this normal approach for creating parts?

I don't think you need to call setVisible(true) and yes tbr is the right
thing to mark things not to be visible.

Did you only ask to make sure you are doing the right thing or does it
not work?

Tom, thank you for reply. This work but i have another problem. When i'm closing my parts i see in profiler that they disposed not immediately and i can open second instance of part. How can i make part singleton?

Can you clarify what you mean with disposed. The MPart instance is not
NOT removed from the model but tbr is set to false only. If it should be
removed from the model when closed you need to tag it with "removeOnHide".
