I m making myself crazy working on this. I have an Entity NamedAgents, WHich has a tomany relationship to an Entity NamedManagedOrgAssoc, which has a toOne relationship to a table calledorganizations.

So an agent can have multiple organizations that they manage. Theentity ManagedOrgAssoc is an associative entity containing apersonIdentifier and an organizationIdentifier. The relationshipfrom agents to ManagedOrgAssoc is tomany, the relationship fromManagedOrgAssoc to organization is to one.


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

both of these attributes (personIdentifier andorganizationIdentifier) 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 correctlisting 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 errorjava.lang.ClassCastException:com.webobjects.eocontrol._EOCheapCopyMutableArray. I have includedthe stacktrace at the end of this message.


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