[rules-users] Logic in the when clause

[Zevenbergen, Alex]

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
