I have the same problem as I'm trying to create a decision table via excel where the fact is a root object A where A has a collection B, and B has a collection C. My rules are based out of the instance A, loop for each object in B, and within that, loop each object in C. Not sure how I can write an expression for the same.
From the examples, I see that one can access a particular element in A by $a.listname[1] but in my case, I need to access all elements in the loop. Any suggestions? prasad raju sagi wrote: > > Hi , > > I am trying to create rule on a fact , which contains arraylist of > collection and the object in the collection internally contains an > arraylist of another collection of objects. > > This looks like object A contains collection of objects B and B contains > collection object C > > A -> blist ( Arraylist ) > > B -> clist (ArrayList<C> ) > > C-> dlist( ArrayList<D>) > > D-> type ( string) > > I am inseting A as fact to the working memory. > > I am in confusion state like how to write the rule to place conditions on > collection C. > > Can I use from in the form of nested from in rule statment. > Thanks > Prasad Raju Sagi > Mobile: 847-644-4103 > > > > > ________________________________ > From: Aziz Boxwala <boxw...@yahoo.com> > To: rules-users@lists.jboss.org > Sent: Thursday, June 11, 2009 1:58:28 PM > Subject: [rules-users] process order example not working fully > > > I am trying to execute a ruleflow and use rules to assign tasks within the > ruleflow in Drools 5.0.1.
