Okay, bear with me. I'm a D2W-novice...
I must be missing something. How does D2W know what Entity that this new page configuration will be for?
I'm currently getting:
IllegalStateException: Couldn't find the dynamic page named QueryTeacherPerson in your DirectToWeb model.entity is null, it seems that one model, maybe ERDirectToWeb d2w.d2wmodel is not loaded!

I want to have individual search screens for each with different search criteria, but since they are all the same entity I don't see how I can follow the normal D2W convention of D2W.factory().queryPageForEntityNamed(entityName, session()) because they are all really the Person Entity.
