Hello all.
I have been researching and I only found somebody who had the same problem, but
the question went unsolved, so Im sorry if I ask again, I hope somebody can
enlighten me.
I have a NSCollectionView and its respective NSCollectionViewItem, also I have
a NSTableView wich displays the properties of an Entity VERSION, The
NSCollecitonView contents its bound to the selectedObjects of this table, so
one I select something (1 or more) I see that the view I designed for the
NSCollectionViewItem appears with the properties of VERSION (which were bound
to the NSCollectionViewItem as representedObject.number , etc).
Now problem is that VERSION has a to-many relation with a entity called
FILES_PER_VERSION, and in the view of the NSCollectionViewItem need to display
in a table the properties of this entity.
I have tried using directly IB bindings but that doesnt seem to work. So I
subclassed NSCollectionViewController and add a NSArrayController as an ivar
called representedToVersionFilesArrayController.
then in the setRepresentedObject Im doing the following:
-(void)setRepresentedObject:(id)representedObject{
[super setRepresentedObject:representedObject];
if([[representedObject entity].name isEqualToString:DPA_VERSION_KEY] ){
NSLog(@"DP Analyzer >>> represented Object is kind of entity
DPAVersionFile");
DPAVersion * ver = (DPAVersion *)representedObject;
NSLog(@"DP Analyzer >>> Got version files ");
self.representedToVersionFilesSet = [[NSArrayController alloc] init];
[self.representedToVersionFilesSet setAutomaticallyPreparesContent:YES];
[self.representedToVersionFilesSet setEntityName:DPA_FILE_VERSION_KEY];
[self.representedToVersionFilesSet
setManagedObjectContext:[(DP_AnalyzerAppDelegate *)[[NSApplication
sharedApplication] delegate] managedObjectContext]];
[self.representedToVersionFilesSet bind:@"contentSet" toObject:ver
withKeyPath:DPA_VERSION_TO_VERSION_FILES_KEY options:nil];
}
}
and then in IB in the table with is inside the view of the
NSCollectionViewController (or in this case my subclass of it), Im binding each
table column to
representedToVersionFilesArrayController.arrangedObjects.<property_of_FILES_PER_VERSION
results nothing yet, so i dunno what am i missing or doing really bad. I have
checked that [ver valueForKey: DPA_VERSION_TO_VERSION_FILES_KEY] is returning
me an NSSet with the entities related to ver, so there is data, but I hadn't
been able to bind it to the table.
Any suggestions?
Please ?
thx
Gustavo
