Hello, 

I wanted to see the impacts of  the system "Aluminium, Knetlegierung_LCI" from ProBas+ Data base. I did not make any change to it, I just tried to create a product system directly from the process. 
I got a java.lang.NullPointerException Error and then the product system does appear BUT if I calculate it no results appear. 

I tried to do the same to other existing processes and the same error happens. I validated the processes and all is fine. What could the mistake be? 

Error Panel (in case it helps) :

java.lang.NullPointerException

(Continuation of the question) -Althought the error occurs when I create a product system from the process,  I am able to see results if I go to the "impact analysis" tab inside the process window
