Kris Verlaenen commented on JBRULES-769:
----------------------------------------
Could you include the drl file that was opened when this error occured? When looking at the code, it seems that the only way a NPE could have occured is when the parser returns a RuleDescr which contains null as one of its AttributeDescrs. This should not occur and we might be able to correct this error if we know which drl caused this error. I will update the code of the outline viewer so the NPE will not occur, even in these circumstances.
