And after all this good tips, you might think about factory methods for each
class like this:
public static MyClass newMyClassForYourRelatedEOs ( EOEditingContext ec,
MultipleParameter myRelatedEOs )
{
MyClass newObject = new MyClass ( ec );
// set your initial relationships
newObject.addObjectToBothSidesOfRelationshipWithKey ( myRelatedEO1,
"myRelation1" );
newObject.addObjectToBothSidesOfRelationshipWithKey ( myRelatedEO2,
"myRelation2" );
//
return newObject;
}
The final setup can follow here:
public void awakeFromInsertion ( EOEditingContext ec )
{
super.awakeFromInsertion ( ec );
// set your initial values
}
Validating might be a nice idea too:
public void validateForSave () throws NSValidation.ValidationException
{
// do your validation first (i prefer this, because super.validateForSave
returns always english error messages, so i try to validate before super and
display my own colloquial)
super.validateForSave ();
// or do your validation last for all remaining errors
}
