Hi, I am trying to use Drools and I would like to check whether such scenario could work: I have facts Document and Line (EJB3 beans, in fact). And Document class has attribute: List<Line> lines So - I would like to pass to stateless session a Document instance "document" and I would like to write rule, that 1) create some new Lines; 2) calculates total from lines; 3) updates document.total; 4) add new Lines instances, that where created during the rule execution to document.lines; And at the end of execution of this session I will like to do some other things with document and document.lines, e.g. persist in database. So - can Drools handle such create of associations during the session execution? Thanks!
