Did you download the IPC sample from Portletswap.com?
Some of the calls have changed in the api from 2.2 to 2.4.
Yes, I downloaded the HellowWorldIPC and uncommented the
newEvent.setWindowState(WindowState.MAXIMIZED); in HelloWorldPortletB Listner
But the maximized state is notworking. I am still facing the same problem
Thanks for your reply.
