I have an application which use some dependency utilities. The utility returns few classes/objects that I want to use in client side. I have included source for those classes through inherits in my module , but since those classes has other internal dependency classes, GWT ask is now asking me to inherit source code for all those classes too. Should I just go ahead and source for all those classes ? Note I am not getting any compilation error in Eclipse but getting No source code found errors while running.
