Hi,
Is is ok to call "defaultEditingContext" everytime I make a changes
in the database?
Because I can no longer make any changes in the database/table
everytime I call "saveChanges" method.
I have this code;
Assuming that there is a String varialble name "Fname" and "Lname"
in the session.
E_Person person=new E_Person()
EOEditingContex ec=session().defaultEditingContext();
Session session=(Session)session();
NSMutableDictionary criteria=new NSMutableDictionary();
criteria.setObjectForKey(session.Fname,"FName");
criteria.setObjectForKey(session.Lname,"LName");
NSArray searchResult=new NSArray();
searchResult=EOUtilities.objectsMatchingValues
(ec,"E_Person",criteria);
if(searchResult.count()>=1){
Is the execution getting to this point? If not, your qualifier is
perhaps wrong, there is no data in the database etc.
If it is getting here, but the save not updating the database, check
to ensure that you are not violating a commandment:

Chuck
person=(E_Person)searchResult.objectAtIndex(0);
person.setFName("New Name");
person.setLName("New Surname");
ec.saveChanges();
}
the code above will not produce an error but it wont make any
changes in the Entity either...
