I m making myself crazy working on this.  I have an Entity Named Agents, WHich has a tomany relationship to an Entity Named ManagedOrgAssoc, which has a toOne relationship to a table called organizations.

So an agent can have multiple organizations that they manage.  The entity ManagedOrgAssoc is an associative entity containing a personIdentifier and an organizationIdentifier.  The relationship from agents to ManagedOrgAssoc is tomany, the relationship from ManagedOrgAssoc to organization is to one.

Agents relates to ManagedOrgAssoc via PersonIdentifier
ManagedOrgAssoc relates to organization via organizationIdentifier

both of these attributes (personIdentifier and organizationIdentifier) are primary keys in their respective entities.

I want to use a WOToManyRelationship control.

I put in the following
datasource:
sourceObject: agents
sourceEntityName: "Agents"
relationshipkey: "mgtOfc"

When I do this the wo relationship does not even display in the form.

I put in the following
datasource:
sourceObject: agents.mgtOfc
sourceEntityName:  "ManagedOrgAssoc"
relationshipKey: "orgs"

When I do this the WO relationship does display and shows the correct listing of data that a user should choose from.  But if I select one (or many) and press save, saving changes to the EO, i get the error java.lang.ClassCastException: com.webobjects.eocontrol._EOCheapCopyMutableArray.  I have included the stacktrace at the end of this message.

Is this something I have done wrong?  Thanks for all your help.
