Edson, Thanks for the tip - you are right - 'return' keyword should not be used - got to this one by trial & error just before I saw your reply :). The problem is that the only 'public' docs available on the new functionality (Wiki 3.1 release notes: http://wiki.jboss.org/wiki/Wiki.jsp?page=3.1M1ReleaseNotes) gives the example of 'accumulate' keyword where 'return' keyword IS used in the 'result' section! So, I guess this needs to be updated?.. Interestingly, "eval ($count < 4)" DOES work correctly and as expected! So, I guess that's an extra feature? :) Thanks for the example on how to avoid eval altogether - already tried it and it works like a charm! Nice functionality! Would it be worth it to include this in Wiki?

Vlad, You should not use the "return" keyword and the ";" inside the result block as it is implicit. Also, remember that anything inside eval() is pure java code, so you cant do $count < 4 if $count is an Integer object. Finally, try to always avoid eval() when writing rules. Try something like: *rule* "FG.23C" *when* *exists* Record( $psc : psc == "323", pa == "7[0-9]*", sa == "F39040" |== "F38010" |== "F38090" ) $count : Integer( intValue < 4 ) *from* *accumulate *( Record( psc == "323", pa *matches* "8[0-9]995", sa *matches* "F390[4-8][2-5]" ), init ( *int* count = 0; ), action( count += count; ), result( *new* Integer(count) ) ) *then* System.out.println( "rule FC.23C has failed" ); System.out.println(); *end* ** Please, let me know if it works.
