can any one help in iterating an arraylist holding finite no of objects, each individual objects holds the details of the object.. for example Boxlist holding different box objects and individual box object holds the detals of box color,box length and etc..please give me the DSL syntax for iterating this box list...and syntax should support the condition such that we should assert the boxlist object (i.e mylist object as per the below conditons) in to working memory.. here BoxList is the class extends ArrayList BoxList mylist=new BoxList(); mylist.add(new boxclass("red","10","20","5"); mylist.add(new boxclass("red","40","20","10"); mylist.add(new boxclass("red","50","40","20"); . . . etc are added in to mylist plz explan the syntax clearly as i had seen some syntax which is confusing me.... thanks vijay -- View this message in context: http://www.nabble.com/list-iteration-tf3375504.html#a9393812 Sent from the drools - user mailing list archive at Nabble.com.
