[rules-users] Problem in writing rule and apply DSL

Hello guys, I really need your help. I'm writing a DSL file in order to allow my application user to write their simple rules. I have queries of this typology: $a: Data( ) $b: Year( ) from $a.years $c: Person( ) from $b.persons dsl mapping (inline version): there are persons=$a: Data( ) $b: Year( ) from $a.years $c: Person( ) from $b.persons now if i would add attribute to person i can't, for example to get persons over 18 years old. If i write: there are persons - age more than 18 drools engine try to add attribute to Data object, probably because it is first object in line. To resolve this problem i should write query something like: $c: Person( ) from ( Year( ).persons from Data( ).years ) In this way i can add attribute to Person instead of Data. Unfortunatly i don't know how can i get it. Someone can help me please. Best Regards -- View this message in context: http://drools.46999.n3.nabble.com/Problem-in-writing-rule-and-apply-DSL-t...
