User Rightmanagement for Parts [message #1769501]

Hi,

I implemented an e4 RCP application and i have user with differned rights. For these rights i want to hide parts for the user. Now is the question how can i do that in e4?

In e3 i know that i can do that with a perspective class that implements the IPerspectiveFactory.

For my e4 application i search for a solution and find that i can define a handler for the part that execute this code below:

 @Execute
   public void execute(MApplication application, EPartService partService,
            EModelService modelService) {
       final MPart part = partService.findPart("partID");
       partService.hidePart(part);
   }

The only problem what i have is that my handle will not be executed, so how can i combine the part with the handler?

I also try to hide the parts in the lifecylcemanager, but i get the execption that the window is not ready and the part cannot be found.

Regards,
Patrick

I found a way to hide the part but i get InjectionException.

I do the hide in the init() method:

@PostConstruct
	private void init(EPartService partService) {
		MPart part = partService.findPart("part.id.activity");
		partService.hidePart(part, true);
	}
