Ok, so maybe this will seem like a scavenger hunt, but...
} else if (d2wcontext.entity() == null) {
reason = "entity is null, it seems that one model,
maybe ERDirectToWeb d2w.d2wmodel is not loaded!";
So it's looking in the d2wContext for your entity. So, check your
rules...
10: true => entity = entityForPageConfiguration [ERDKeyValueAssignment]
and
0: true => entityForPageConfiguration = <blah>
[ERDDefaultModelAssignment]
So, checking ERDDefaultModelAssignment.java we find
public Object entityForPageConfiguration(D2WContext c) {
return entityForKey(c, "pageConfiguration");
}
protected Object entityForKey(D2WContext c, String key) {
Object result = null;
if(key != null) {
result =
ERXEOAccessUtilities
.entityMatchingString
((EOEditingContext)c.valueForKey("session.defaultEditingContext"),
(String)c.valueForKey(key));
}
if(result == null && isTaskWithoutEntity(c.task())) {
result = dummyEntity();
}
return result;
}
So it appears to be looking up the entity using the static method
ERXEOAccessUtilities.entityMatchingString and returning null.

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!

Obviously, you need to know what exactly you are looking for in
advance.

Hi D2Wers,
I've got the Entity "Person" in my model that can have a type of
Student, Teacher, Parent, etc. They are not subclasses because it
is entirely possible for a Person to be both a Teacher and a
Parent simultaniously. 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.
What's the best way to approach this with D2W?
Thanks,
Dave
