Hello;
Agents is a single row. mgtOfc is a relationship key. Even when I do:
sourceObject: agent
sourceEntityName: "agents"
relationshipKey: "mgtOfc"
destinationDisplayKey = "orgs.name"
The listbox does not show on the screen when the screen is rendered
in the application.
Sorry for being so dense.

I want to use a WOToManyRelationship control.
I put in the following

sourceEntityName: "Agents"

sourceObject should be bound to a key that returns an
EOEnterpriseObject not an array of objects.
is "mgt0fc" a toMany relationship?
When I do this the wo relationship does not even display in the form.
I put in the following
datasource:
sourceObject: agents.mgtOfc
Again, if "agents" is an array, then agents.mgtOfc is going to
return an array containing the results of performing mgt0fc on each
agent in agents. If agents is badly named and does indeed return an
EOEnterpriseObject (and not one within an array) then agents.mgt0fc
looks like it would be an array rather than a single object.
You should have something like:
sourceObject = myAgent;
sourceEntityName = "Agent";
relationshipKey = managedOrgAssociations;
destinationDisplayKey = "organization.name";
