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

sourceObject: agents
sourceEntityName: "Agents"
relationshipkey: "mgtOfc"
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";
Check out the api for WOJExtensions:
