Finally figured out the problem. Here is how I zoomed in the solution.
1) To see if the problem is in the way I hooked up the
TOManyRelationship or coded my objects, I created a Direct2Web apps
based on my eomodeled. The problem persisted. The D2W apps crashed.
2) So I assume it was either in my eomodel or in the database. I then
compared my eomodel to some examples (Movies.eomodeld). Nothing
seemed out of place.
3) I decided to inspect the databse and the data and realized that my
NetWorkInterface contained a foreighn key that could be null (because
a network interface card can exist without being installed into a
comptuer) but the way the database was initialized, those foreign
keys were set to 0 and not set to null ( I used phppgAdmin ot inspect
and set all my foreighn keys to null). Everythign started working
nicely.
What was hapenning was tha upon assigning a networkinterface to a
networkdevice, it had to first remove the networkinterface from its
previous networkdevice but
since that foreighn key was not properly identiified as null, but as
0, it looked for a networkdevice with primary key 0 (which didn't
exit) and crashed.
I was stumped for so long because the error message:
java.lang.IllegalArgumentException: removeObjectToPropertyWithKey:
the key networkinterfaces is not a Array or one of its subclasses -
unable to remove the value
really pointed my towrad an object/class typing error.

Ok, I've been banging my head for more than 2 weeks on this one.
Moved to something else to get some distance, But I still can't fix
this.
Background:
I'm trying to develop a small app (as a too an learning experience
before moving on to something bigger) to manage our ip addresses and
generate automatically (eventually the dns configuration files). I
have NetworkDevices (computers, printers...) and NetworkInterfaces (
actual ethernet cards, wifi, .... ) entities. One NetworkDevice can
have multiple NetworkInterface (where the to many relationship
happens).
The java code is the one generated automatically by EOModeler, no
modifications (see below shortened versions)
In the wod, my WOToManyRelationship is wired as
ToManyRelationship: WOToManyRelationship {
sourceEntityName = "NetworkDevice";
sourceObject = networkdeviceDisplayGroup.selectedObject;
relationshipKey = "networkinterfaces";
destinationDisplayKey = "ethernet";
}
Also it is in a WOForm (with multipleSubmit set to true because I
have multiple summit buttons 8-).
Problem: Exception is thrown when I try to save changes after
changing selection in the WOToManyRelationship
java.lang.IllegalArgumentException: removeObjectToPropertyWithKey:
the key networkinterfaces is not a Array or one of its subclasses -
unable to remove the value.
