[rules-users] comparison of two variables on same object, JBoss Rules 3.0.6

[Edson Tirelli]

    Unfortunately, in 3.0.6, the only way is using eval in a subsequent
pattern:

when
    Tree( $old : old, $new : new )
    eval( $old.intValue() > $new.intValue() )
then
    // do something
end

    Also, remember that 3.0.6 auto-wraps any primitive value, so the need to
use the .intValue() method calls as you see in the eval() above.

    4.0 shall be released later this month, so, hopefully we will not have
to deal with 3.0.x limitations for much longer.
