Hello all. I have a situation. :S. I have the follow entities and relations: Invoice< >> ItemXInvoice<< > Item.. The Entity ItemXInvoice has attributes quantity and totalItemPrice, and the Item has, descr (description) and unitPrice.
An Instance of NSArrayController for the entity ItemXInvoice Now I have an NSTable, with 4 columns, Description, Quanity, Unit Price, and TotalPrice. and its model key path biding to: Description Column : toItem.descr , Quantity : quantity. UnitPrice: toItem.unitPrice totalItemPrice: totalItemPrice. so when I click add, it creates a ManageObject ItemXInvoice and insert it into the NSArrayController, but of course when I try to put something in the columns, Description and UnitPrice, when I exit the field it disappear because the Item for that ItemXInvoice doesn't exist... (thats what I am thinking, am I right?). So I guessI have to implement a custom class of NSArrayController, and be this one the class for the Instance of the controller for ItemXItem, then override the method add, and there ... what shall I do? create the NSEntityDescription for Item and set the relation to what? I dunno what to do here.. any ideas?
