Re: [rules-users] Comparing Date with || OR operator
Guys, I don’t know if there is a bug in Drools while comparing Date attributes. I am trying different things. Another finding is the following code works. Membership ( $regDate : regDate) Segment ( startDate < $regDate || startDate.time > endDate.time ) It solves my problem but makes code bit ugly and lengthy.

I just read you condition. You are building $endDate to Segment.endDate and than comparing Segment.startDate with $endDate what is same as comparing Segment.startDate with Segment.endDate -> transition principle.

Hi Pavel I really don’t understand what do you mean. I guess you didn’t read complete thread carefully. Assigning endDate attribute in a variable and not using that variable in condition make no sense to me.

Re: [rules-users] Comparing Date with || OR operator
Have you got the stack trace, that may give a clue? Also what are the actual values of start date and end date?

Re: [rules-users] Comparing Date with || OR operator
If it works fine with an and operator then I’d imagine that startDate < $regDate returns false, with an && this would abort evaluation immediately but with an or it would mean that startDate > endDate is evaluated and so presumably it is this bit that is throwing the NPE.
