Hi Jens,
I apologize for the delayed reply since we're getting behind schedule with our next release that many are waiting for.
I checked your app, and the 'taskDef' you're working with in MasterViewController.m is not the same 'taskDef' that you defined in your Storyboard, and hence any actions you set never get called. You shouldn't be declaring a new taskDef, but rather accessing the one you already created in IB using the following:
SCEntityDefinition *taskDef = (SCEntityDefinition *)[self dataDefinitionWithIBName:@"TaskEntity"];
Also, please note that you don't need to define the action on two stages as you did in the project (first you did willConfigure then saveImage). All you need is simply this:
imagePropertyDef.cellActions.saveImage = ^(SCImagePickerCell *imagePickerCell, NSIndexPath *indexPath, NSString *imagePath)
{
UIImage *myImage = imagePickerCell.selectedImage;
NSManagedObject *myCoreDataObject = (NSManagedObject *)imagePickerCell.boundObject;
// Convert the myImage to binary here then write it in myCoreDataObject
};
Same thing for loadImage. Hope this helps.
