All, I have the following rule which uses the collect function: rule "Invalid RR Line" salience 100 when rrDetailLine : DetailLine(detailKeyRecNo:keyRecNo != null, lineNumber != null ) rrHeader : ArrayList( size == 0 ) from collect(RrHeader( keyRecNo != detailKeyRecNo )) then // logger.debug("Invalid RR Line: " + rrHeader.size()); logger.debug("Invalid RR Line: " + rrDetailLine.getKeyRecNo()); logger.debug("Invalid RR Line: " + rrDetailLine.getLineNumber()); drools.halt(); end What I am seeing is that if I only have 1 RrHeader in working memory this rule fails. Th reason I know that there is an RrHeader object is that I change the rule to the following: rule "Invalid RR Line" salience 100 when rrDetailLine : DetailLine(detailKeyRecNo:keyRecNo != null, lineNumber != null ) rrHeader : RrHeader( keyRecNo != detailKeyRecNo ) then // logger.debug("Invalid RR Line: " + rrHeader.size()); logger.debug("Invalid RR Line: " + rrDetailLine.getKeyRecNo()); logger.debug("Invalid RR Line: " + rrDetailLine.getLineNumber()); drools.halt(); end And it worked just fine.

Edson, Dulp...you just made me realize what the issue is. Stupid Developer! Thanks!
