While trying to find out why some data did not get saved. I discovered in Debug
mode that all kinds of fetches did return an exception, which in turn caused
the ERXEC to not do it's thing and save the data in it's EOEditingContext.
Removing the fetches that created the Exceptions in a RR-loop resulted in
saving the data.
But I do not understand where these Exceptions come from.
Two Examples:
Here I am fetching some program settings, and the program creates an Exception
(I assume) at
nl.netsense.theater._ProgramSetting.isTest(_ProgramSetting.java:48). This is
just an Integer, which is allowed to be empty (0 in the EOModeler setup).
NSMutableDictionary currentbindings = new NSMutableDictionary();
currentbindings.setObjectForKey( today,"currentdate");
// Get the programsettings: for use of (eg) VAT, name of
theater, etc.
NSDictionary settingsbindings = currentbindings;
NSArray settingsList =
EOUtilities.objectsWithFetchSpecificationAndBindings(myEc(),"ProgramSetting",
"currentSetting", settingsbindings);
setCurrentProgramSetting(
(ProgramSetting)settingsList.objectAtIndex(0));
Why would ERXEC create an Eception on something like this?

Second example:
I am fetching a bunch of tickets, based on the premisse that the person behind
the cashregister is the one that sold the ticket, and that it is a ticket that
has no creditcard affiiation:
NSMutableArray qualArray = new NSMutableArray();
qualArray.addObject( new
EOKeyValueQualifier("ticketPaydeskSessionId",
EOQualifier.QualifierOperatorEqual, currentPayDeskSession().paydeskSessionId()
) );
qualArray.addObject( new
EOKeyValueQualifier("lineItem.order.cardtype",
EOQualifier.QualifierOperatorEqual, null ) );
Object orderings[]={
EOSortOrdering.sortOrderingWithKey("ticketDateSold",
EOSortOrdering.CompareAscending)
};
EOQualifier andQualifier = new EOAndQualifier( qualArray );
EOFetchSpecification spec = new
EOFetchSpecification("TicketSold", andQualifier, new NSArray(orderings) );
spec.setRefreshesRefetchedObjects(true);
printedTicketList = ec.objectsWithFetchSpecification(spec);
return printedTicketList;
This also results in a Exception.
