I have a injected view part class: TestView and a handler class: TestHandler.
And I wish to obtained the exact injected TestView object, could somebody tell me how to do that please?

I've tried to use PartService.getPart(), but this only give me a MPart object.
I've also tried use ContextInjectionFactory.make(), but this creates a new TestView object instead of the one used as my view.

Thanks.

I've tried add

 @Named("viewId") TestView test View

as a parameter of the handler's execute() method but still not working

MPart.getObject() and cast it to your runtime class.

Did you inspect the MPart instance - believe me you'll find a method
there to give you the instance of your view.

Thanks.

Also, may I ask if I am using the "best practice" here?
What I want to do is to set some data that is associated with the TestView class. So I try to obtain that object and then set it's attribute.
In eclipse 4, is there any "standard practice" to solve this kind of problem? such as using IEventBroker to post the data.

there are 2 ways:
a) send an event using IEventBroker
b) set the value in the IEclipseContext of the part or one of the parent
contexts
