How to Raise a class event from webdynpro

Hi Experts..

I am trying to raise an event which is defined in a Class(which is not my assistance class) in my WD comp.

I clicked on Pattern and selected option  Raise event, I gave the class name and selected the event which should raise.

But I am getting an error.

CL_<VIEW NAME>_CTR does not have  an event.

Thanks,

Pradeep.
