FAQ
Hi,
When I have a "one to many" relationship between two entities I have
something like this:

// obj1 is an instance of Entity1
List<Entity2> listObj2 = obj1.getEntity2Array();

Is there a way to filter values on listObj2 by an attribute value?

Thank you.

    Hello Andres,

    You can create an Expression and then use filterObjects on it. See the
    bottom of:
