Subject: [rules-users] doubt in using collections and nested objects<br>To: <a href="mailto:rules-users@lists.jboss.org">rules-users@lists.jboss.org</a><br><br><br>Hi All,<br>
<br>
<br>
I have a scenario which is similar to the one detailed below<br>
<br>
There is a class Student and each students has a list of subjects.<br>
Each subject has a name and a flag which is an indicator of pass or<br>
failure.<br>
<br>
Now how can I write a rule which tells me if there are atleast 10<br>
students who failed in a subject maths.<br>
<br>
Thanks<br>
sudhir.<br>
