in your validation method, change

executeFetchRequest:allSpeciesIDsFetchRequest error:nil];
NSArray *allCatalogIDs = [allSpecies valueForKeyPath:@catalogID];
if ([allCatalogIDs containsObject:*ioValue]) {
to something like

Re: Converting database to Core Data
Perhaps I don't see the problem but what is preventing you from creating the second inverse relationship? Op 10 jul 2014, om 22:00 heeft William Squires het volgende geschreven: I'm trying to convert the following. I have two tables in a database, TransactionEntry, and ReasonCode. A TransactionEntry record is just a posting from a POS (Point-of-Sale) terminal, and has these fields (of interest): Table (TransactionEntry) ID As Int32 PrimaryReasonCode As Int32 // both of these link to ReasonCode.ID SecondaryReasonCode As Int32 ... and a ReasonCode record is used when a certain types of transactions occur, such as POSItemReturned, POSItemVoided, POSCommError, and a few others. Table (ReasonCode) ID As Int32 Description As Varchar(50) ReasonCode As Int16 // just an enum ... All would be good and well if the TransactionEntry table had only one reference (.PrimaryReasonCode) to the ReasonCode table, but some transactions (such as a voided item) require the manager to fill in both the primary and secondary reason codes. I can create the entities, and replace the Int32 record numbers/IDs with a relationship. I create the relationship in entity TransactionEntry and set it to ReasonCode, leaving the inverse relationship to none for now. I then create an inverse relationship in entity ReasonCode to refer back to TransactionEntry. Now I can create the inverse relationships in both directions. 1:1 for TransactionEntry - ReasonCode, and 1:many for ReasonCode - TransactionEntry. All okay so far. Primary ReasonCode records (entities) are re-used to save memory, and the .Description fields are pre-set to values such as, return item, wrong key hit, cc reader not working, etc... Secondary ReasonCode entities are (usually) created on-demand from the POS terminal when the manager logs in. A few are re-used, but mostly new entities are created. The problem now comes when I try to create the same relationships from TransactionEntry entities to ReasonCode entities for the secondary reason code records (entities), since it won't let me make both inverse relationships 1:many from ReasonCode back to TransactionEntry. Is this a limitation of CoreData? Or is there a way around this? Can I ignore Xcode's warnings about not having inverse relationships, and simply set the inverse relationships from the TransactionEntry entity(ies) to the ReasonCode Entity to none, and simply get rid of the inverse relationships in the ReasonCode entity?

Re: Set up an editable view based NSTableView programmatically - how to?
Op 7 jan 2014, om 16:52 heeft Peter het volgende geschreven:
I’d actually prefer to use bindings, but my first column should simply
display the row numbers
After some experimenting I managed to create a simple editable view based table
view with row numbers, using bindings except for the row number. The row number
is in a column with identifier RowNumber. I implemented this delegate method:
- (NSView *)tableView:(NSTableView *)tableView
viewForTableColumn:(NSTableColumn *)tableColumn
row:(NSInteger)row
{
NSTableCellView *result = [tableView
makeViewWithIdentifier:[tableColumn identifier] owner:self];
if ([[tableColumn identifier] isEqualToString:@RowNumber])
result.textField.objectValue = [NSNumber numberWithInteger:row];
return result;
}
That's all.
This is the first time I used a view based table view and it looks too simple
but maybe it helps.

Re: NSPopUpButton binding value/selected problem
Why don't you want to bind the Selected Index? It does what you want. Because I don't want the menu to reflect the selection in the table. I just need the contents of the menu to match the contents of the table, but the selections in each place need to be independent of each other. You could bind Selected Object of the popup button to something like a property of the windowcontroller. Or give the popup button its own arraycontroller.

How to create an expression?
hi, How do I programmatically create the $x.firstname and .@count parts of this expression? SUBQUERY(residents, $x, $x.firstname == Jane $x.lastname == Doe).@count When I create a subquery predicate with predicateWithFormat:, the class of the $x.firstname and .@count expressions is NSKeyPathExpression and the type is NSFunctionExpressionType. The operand is an expression of type NSVariableExpressionType or NSSubqueryExpressionType. The function is valueForKeyPath:. When I create an expression with expressionForKeyPath:, the operand is SELF instead of the variable or the subquery. When I create an expression with expressionForFunction:selectorName:arguments:, the class is NSFunctionExpression. When the argument is a keypath expression, instead of $x.firstname the expression tries to evaluate $x.Jane and that doesn't work. executeFetchRequest throws an exception: -constantValue only defined for abstract class. Define -[NSKeyPathExpression constantValue]! If the argument is a constant value expression, executeFetchRequest throws an exception: -keyPath only defined for abstract class. Define -[NSConstantValueExpression keyPath]!. The predicate will be edited in a rule editor so I have to convert it to criteria and back. The predicate will be used as filter predicate of an array controller in entity mode and/or in a fetch request with Core Data (SQLite).
