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

[Sudhir M]

Hi All,


I have a scenario which is similar to the one detailed below

There is a class Student and each students has a list of subjects.
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.
