The following code generates NPE in ReteTuple.java
rule
when
Membership ( $regDate : regDate)
Segment ( startDate < $regDate || startDate > endDate )
then
System.err.print(“Invalid start date”);
end
I am new in Drools and don’t know much about DRL scripting. It works fine I
use && operator instead.

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. I’d imagine that the most likely reason for this would be that
endDate is null.
Try changing it too
Segment ( startDate < $regDate || (endDate != null && startDate > endDate)
)
And see whether you loose the NPE.

Hi Thomas
Thanks your prompt reply. I am sure all three attributes are NOT null. I have tested them

Have you got the stack trace, that may give a clue? Also what are the actual values of
start date and end date?

What about:
Membership ( $regDate : regDate)
Segment ($endDate : endDate, startDate < $regDate || startDate > endDate )
Logically startDate > endDate doesn't make sense but it should work ;-)

I tried with some thing different and it worked but I don’t want this
as I
have many collections in my data structure.
//this works
Membership ( $regDate : regDate)
Segment ( $endDate : endDate )
Segment ( startDate < $regDate || startDate > $endDate )
//this does NOT work
Membership ( $regDate : regDate)
Segment ($endDate : endDate, startDate < $regDate || startDate >
$endDate )

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

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.

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.

Subject: Re: Comparing Date with || OR operator
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.
