Re: [rules-users] "collection contains" problem
Mike,
Wolfgang has it right. When you write:
property : StatusProperty( name == "propertyName", value ==
"valueA" )
You are telling the engine that the StatusProperty is a fact in the
working memory. Reading that, I assumed you were inserting them, because if
they are not facts in the working memory, the rule will obviously never
match.
If you don't want to insert them (although recommended), you need to
rewrite the pattern using "from" to tell the engine where to look for the
properties. Example:
when
t : TrainingStatus( currentSection == "section_a" )
property : StatusProperty( name == "propertyName", value ==
"valueA" ) from t.properties
then
end

Hello Wolfgang,
Thank you for the response. However, as I read this documentation this
should not be necessary. Even still, if I try it, it does not seem to help.
Thanks,
Mike

Only because you mention the insertion of the TrainingStatus object but not
the one(s) of (a) StatusProperty object(s): They should be inserted, too!
