Hi All,

I have the problem with swithching from one application to another.There are two applications like X and Y. When I first select X , it works fine without any errors.When I switch from X to Y , it was giving the error as Null pointer Exception.it won't get the screen.Both X and Y Bussiness code was written in the same java file.But the controller and view are different.and also the Java file was mentioned as Singleton.


Anybody could you help me regarding this.

No buddy, this forum is only for SCJP, I can see controller, view, business code in your questions, it feels like SCWCD or something else.
