NSOutlineView: eccezione quando si modifica un NSTextFieldCell associato a un NSTreeController

Question

Si verifica un arresto anomalo quando si modifica un NSTextFieldCell (immediatamente dopo il clic e il cursore inizia a lampeggiare), in un NSOutlineView.

La colonna della tabella è associata all'origine dati. I valori sono visualizzati correttamente nella cella, il binding funziona, ottengo problemi solo quando modifico la cella.

[theEditingColumn bind:@"value" myTreeController withKeyPath:[NSString stringWithFormat:@"arrangedObjects.%@", metadata.columnBindingKeyPath] options:bindingOptions]; 

Questa è l'eccezione che ottengo. Sembra che NSTextFieldCell stia impostando/ottenendo valori da NSControllerTreeProxy anziché dal contenuto di NSTreeController.

Immagino che l'associazione funzioni bene per visualizzare i valori, ma non per modificarli?

UPDATE ho aggiunto un punto di interruzione simbolica e ottengo il seguente:

po *(id *)($esp + 4) 
<NSTextValueBinder: 0xfe40720>{object: <NSTableColumn: 0xfe40180> identifier: MovieReleaseYear, bindings: value=arrangedObjects.MovieReleaseYear} 

p *(SEL *)($esp + 8) 
(SEL) $10 = "_valueForKeyPath:ofObject:mode:raisesForNotApplicableKeys:" 

po *(id *)($esp + 12) 
arrangedObjects 

po *(id *)($esp + 16) 
<CBTreeController: 0x39b4340>[object class: NSMutableDictionary] 

Answer 1

Recentemente mi sono imbattuto nello stesso tuo problema. Non sono sicuro che sia in ritardo per aiutarti, ma continuerò a fornire ciò che ha risolto per me.

Non conosco l'intero codice, quindi non posso essere sicuro se è lo stesso problema di te, ma stavo anche cercando di associare una colonna e modificarla in seguito, dandomi lo stesso crash .

È abbastanza semplice infatti. Mi era vincolante colonna prima di aggiungerlo alla vista Struttura come ad esempio:

[theEditingColumn bind:@"value" myTreeController withKeyPath:[NSString stringWithFormat:@"arrangedObjects.%@", metadata.columnBindingKeyPath] options:bindingOptions]; 
[theOutlineView addTableColumn: theEditingColumn] 

non posso dare alcuna spiegazione sul motivo per cui questo è il caso, ma il passaggio è stato risolto dalla mia parte:

[theOutlineView addTableColumn: theEditingColumn] 
[theEditingColumn bind:@"value" myTreeController withKeyPath:[NSString stringWithFormat:@"arrangedObjects.%@", metadata.columnBindingKeyPath] options:bindingOptions]; 

Answer 2

non provate, ma potrebbe lavorare con questa linea.

[theEditingColumn bind:@"value" myTreeController withKeyPath:[NSString stringWithFormat:@"arrangedObjects.childNodes.representedObject.%@", metadata.columnBindingKeyPath] options:bindingOptions];
