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

EODatabaseContext.java 5086

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?
