[rules-users] unable to write a function in guvnor with generic List as a parameter

Hi, I'm trying to write a function in guvnor like function int applyThresholds(List<Integer> thresholdList, int totalPoints) It says the List<Integer> ClassNotFound even though I've java.util.List in the imports. when i remove <Integer> generic it works fine. I'm using drools and guvnor 5.4 CR1. Am I missing anything? Thanks in advance. -- cheers Sumatheja Dasararaju
