  • Remove then Query fails in JPA/Hibernate (deleted entity passed to persist)

    - by Kevin
    I've got a problem with the removal of entities in my JPA application: basically, I do in this EJB Business method: load photo list ; for each photo { //UPDATE remove TagPhoto element from @OneToMany relation //DISPLAY create query involving TagPhoto ... } and this last query always throws an EntityNotFoundException (deleted entity passed to persist: [...TagPhoto#]) I think I understand the meaning of this exception, like a synchronization problem caused by my Remove, but how can I get rid of it?

  • NSSortDescriptor for NSFetchRequestController causes crash when value of sorted attribute is changed

    - by AJ
    I have an Core Data Entity with a number of attributes, which include amount(float), categoryTotal(float) and category(string) The initial ViewController uses a FethchedResultsController to retrieve the entities, and sorts them based on the category and then the categoryTotal. No problems so far. NSManagedObjectContext *moc = [self managedObjectContext]; NSEntityDescription *entityDescription = [NSEntityDescription entityForName:@"Transaction" inManagedObjectContext:moc]; NSFetchRequest *request = [[[NSFetchRequest alloc] init] autorelease]; [request setEntity:entityDescription]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(dateStamp >= %@) AND (dateStamp =< %@)", startDate, endDate]; [request setPredicate:predicate]; NSSortDescriptor *sortByCategory = [[NSSortDescriptor alloc] initWithKey:@"category" ascending:sortOrder]; NSSortDescriptor *sortByTotals = [[NSSortDescriptor alloc] initWithKey:@"categoryTotal" ascending:sortOrder]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortByTotals, sortByCategory, nil]; [request setSortDescriptors:sortDescriptors]; NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:request managedObjectContext:managedObjectContext sectionNameKeyPath:@"category" cacheName:nil]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; On selecting a row (tableView:didSelectRowAtIndexPath), another view controller is loaded that allows editing of the amount field for the selected entity. Before returning to the first view, categoryTotal is updated by the new ‘amount’. The problem comes when returning to the first view controller, the app bombs with *Serious application error. Exception was caught during Core Data change processing: Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (1) must be equal to the number of rows contained in that section before the update (1), plus or minus the number of rows inserted or deleted from that section (0 inserted, 1 deleted). with userInfo (null) Program received signal: “EXC_BAD_ACCESS”.* This seems to be courtesy of NSSortDescriptor *sortByTotals = [[NSSortDescriptor alloc] initWithKey:@"categoryTotal" ascending:sortOrder]; If I remove this everything works as expected, but obviously without the sorting I want. I'm guessing this is to do with the sorting order changing due to categoryTotal changing (deletion / insertion) but can't find away fix this. I've verified that values are being modified correctly in the second view, so it appears down to the fetchedResultsController being confused. If the categoryAmount is changed to one that does not change the sort order, then no error is generated I'm not physically changing (ie deleting) the number of items the fetchedResultsController is returning ... the only other issue I can find that seem to generate this error Any ideas would be most welcome Thanks, AJ

  • factory girl - know when an attribute is overridden in factory

    - by carlos
    Is there any way to determine if attributes are overridden in a factory and adjust the behavior of the factory based on those overrides? The evaluator passed into the callbacks contains a __override_names__ method. Unfortunately, by the time it is passed to the callback, every attribute configured by the factory is included in the array returned. Moreover, the Evaluator is marked as api private.

  • Localization of attribute values in .NET

    - by Alex Angas
    How can I localize/internationalize attribute values in .NET? My specific example is for ASP.NET web parts such as WebDisplayName, WebDescription, etc. where I inherit from the base class that uses these attributes. Also, is there any difference to doing this with attributes declared in my own classes? Thanks!

  • How to make a nested query with an Entity that doesn't really exist (many-to-many)

    - by Calou
    Hi everyone, I'm new with Doctrine2 so my question can be easy to answer (I hope so). First of all, here the SQL query that I'd want : SELECT * FROM Document WHERE id NOT IN (SELECT document_id FROM Documents_Folders) Pretty simple isn't it ? The porblem is that my table 'Documents_Folders' is not an entity. In fact, it was create because I have a many-to-many relation between my entities 'Document' and 'Folder'. I tried several queries, but none worked. Thanks.

  • Extend an entity to create a computed observable that requires a navigation property

    I'm trying to extend an entity to create a computed observable that requires a navigation property: app.domain.indicador = function () { this.ValorMetaActual = ko.computed({ read: function () { console.log(this.ValoresMeta); //navigation property: undefined return 0; }, deferEvaluation: true }, this); }; The problem is that when the observable is created, the navigation property does not yet exist.
