Hi
Not sure if I got it right. I presumed if this is a many-to-many modelling
between Employee and Turn, and the relationship is flattened.
The way I think it should do to add Employee to Turn and Turn to Employee
are as the following:
localEmployee.addToTurns(actualTurn);
actualTurn.addToEmployees(localEmployee);
Then call your save changes. Usually there is no need to
addBothSideRelationshipWithKey to join table e.g. EmployeeXTurn (presumed
again this is join table).
The other thing thought may be useful to check is "propogate primary key" is
ticked between the Employee and its relationship to join table, vice versa
between Turn and its relationship to join table.

Hello, I fixed (or thought I did) the EOmodel, then I did this in my
method.
Employee localEmployee =
(Employee)EOUtilities.localInstanceOfObject(myEC, emp);
System.out.println(selectedItems());
NSArray<Turn> localSelectedItems =
EOUtilities.localInstancesOfObjects(myEC, selectedItems());
EmployeeXTurn empxTurn = (EmployeeXTurn)
ERXEOControlUtilities.createAndInsertObject(myEC,"EmployeeXTurn");
for (Turn actualTurn:localSelectedItems){
actualTurn.addToEmployeeXTurn(empxTurn);
}
System.out.println(localSelectedItems);
empxTurn.addObjectToBothSidesOfRelationshipWithKey(localEmployee,
EmployeeXTurn.EMPLOYEE_KEY);
inside the for I have tried the
addObjectToBothSidesOfRelationshipWithKey() method and the
addObjectsToBothSidesOfRelationshipWithKey() method and im still
getting this error
java.lang.NullPointerException

if I just do this :
empxTurn.addObjectToBothSidesOfRelationshipWithKey(localEmployee,
EmployeeXTurn.EMPLOYEE_KEY);
or this :
localEmployee.addObjectToBothSidesOfRelationshipWithKey(empxTurn,
Employee.EMPLOYEE_X_TURNS_KEY);
all its fine, I can add the employee to the EmployeeXTurn, btu the
problem comes when adding the turn to the EmployeeXTurn.
I think you guys are getting tired of this problems Im having, also I
am, can get it why Im having them.
any clues?
