Well, accesses to embedded objects are a little more complicated, but if
you want it:
rule HomeWinEt
when
$f : Fact( $d : details )
eval( $d.CLOCK_STAGE > 10 &&
($d.HOME_MATCH_SCORE - $d.HOME_FULL_TIME_SCORE >
$d.AWAY_MATCH_SCORE - $d.AWAY_FULL_TIME_SCORE))
then
# ...
end
Consider asserting the objects stored as the Facts.details as well. This
will let you write the much more declarative (and presumably more
efficient) rule with the "return value" restriction:
rule HomeWinEtxxx
when
$d : Detail( CLOCK_STAGE > 10,
HOME_MATCH_SCORE > (HOME_FULL_TIME_SCORE +
AWAY_MATCH_SCORE - AWAY_FULL_TIME_SCORE))
$f : Fact( details == $d )
then
# ...
end

Thanks,
this is the rule:
rule "Home win et"
when
$f : Fact(details.CLOCK_STAGE > 10,(details.HOME_MATCH_SCORE -
details.HOME_FULL_TIME_SCORE) > (details.AWAY_MATCH_SCORE -
details.AWAY_FULL_TIME_SCORE))
then
end

You could use eval( <expression> ) for this, but I guess it
could also be added as a return value field constraint to the last of
these four fields. Would you mind providing the full pattern?

Hi,
quick newbie question about the when clause in a rule.
eg can i get the fact to be tested from the result of two other inputted
facts?
details.HOME_MATCH_SCORE - details.HOME_FULL_TIME_SCORE
details.AWAY_MATCH_SCORE - details.AWAY_FULL_TIME_SCORE
I assumed this would work fine but it doesn't recognise
the '-' as a minus!
Thanks in advance
Alex
