I have been getting this using flattened many-to-many relationships where my join-table has its own primary key (not compound of the two foreign keys). As soon as I quit using a flattened relationship, I quit getting the error.

I don't know if the independent primary key was actually causing the problem or not.

Hi List,
i have a problem to analyse the following error:
java.lang.IllegalStateException: A valid global ID could not be obtained for entity named Class_Hour, relationship named location_Rooms, primary key dictionary {fk_location_room = 5; fk_class = 26; }
Stack:
EODatabaseContext.java 5062 databaseOperationForIntermediateRowFromSourceObject com.webobjects.eoaccess EODatabaseContext.java 5086 recordDeleteForIntermediateRowFromSourceObjectRelationshipDestinationO bject com.webobjects.eoaccess EODatabaseContext.java 5139 nullifyAttributesInRelationshipSourceObjectDestinationObject com.webobjects.eoaccess EODatabaseContext.java 5166 nullifyAttributesInRelationshipSourceObjectDestinationObjects com.webobjects.eoaccess EODatabaseContext.java 6056 recordChangesInEditingContext com.webobjects.eoaccess EOObjectStoreCoordinator.java 412 saveChangesInEditingContext com.webobjects.eocontrol EOEditingContext.java 3187 saveChanges com.webobjects.eocontrol OneClassPage.java 166 deleteClass ....
Code in deleteClass:
theClass.validateForDelete ();          // does not raise!
ec.deleteObject ( theClass );
ec.saveChanges ();
The entities are:
Relations:    Class<-->>ClassHour<<-->location_Room<<-->Location
                                 <<-------------------->
Optional:           opt            opt              opt
                                            opt
Delete Rule:       casc->          null           <-casc
                                            null
"fk_location_room" and "fk_class" from the error primary key dictionary are both in "ClassHour". The relation "location_Rooms" from the error message is from "Class" to "Class_Hours.location_Room", "Class_Hours" is from "Class" to "ClassHours"

When i delete a "Class" with a "ClassHour" assigned, that points to a "Location" and a "location_Room" i get the above mentioned error. (A "location_Room" can only be assigned when a "Location" is assigned before.)
Any ideas for a solution?
