Re: [rules-users] doubt in using collections and nested objects

Hi Sudhir, What you need is an accumulate. I recommend you to read documentation about it. I've attached a test case of your scenario.

Each subject has a name and a flag which is an indicator of pass or failure. Now how can I write a rule which tells me if there are atleast 10 students who failed in a subject maths. Thanks sudhir. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users -- XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX Esteban Aliverti
