[omniORB] application attempted to invoke an operation on a nil reference

[Wittstruck, Nicholas]

Hi, 

thank you for your replies. I was able to fix the issue with your help, you we're right. I get another error now - regardless wether I do anything in the pi method or not, the application crashes after its exceution. I've added my IDL file. Do you know why this happens? 

Thank you btw for the book recommendation :) Ordered it right now.
