Hi,
I am facing this error when I try to edit or create an entity:
UnknownKeyException: [<er.modern.look.pages.ERMODInspectPage name:
er.modern.look.pages.ERMODInspectPage subcomponents: null > takeValueForKey()]:
attempt to assign value to unknown key: 'masterObjectAndRelationshipKey'.
This WOComponent does not have an instance variable of the name
masterObjectAndRelationshipKey or _masterObjectAndRelationshipKey, nor a method
of the name setMasterObjectAndRelationshipKey or
_setMasterObjectAndRelationshipKey

The entity in question has three to-one relationships and the only that is not
set is a to one to an ERDatabaseAttachment. Should this be the reason for the
exception? It is interesting to notice that inspecting the entity doesn't raise
the exception and that I was able to create a new entity without raising the
exception before I entered some data directly in MySQL. It is also noticeable
that I faced this exception when using one but not both of this rules
simultaneously:
100 : pageConfiguration = 'CreateAgency' => displayNameForPageConfiguration =
"Create New Agency" [com.webobjects.directtoweb.Assignment]
100 : pageConfiguration = 'CreateAgency' => navigationState =
"Agency.CreateAgency" [com.webobjects.directtoweb.Assignment]
