ARGOMENTO: Errore modifica linea ordine di vendita

Ciao a tutti,
ho installato da poco Odoo 8.

• Ho installato solo i moduli Vendite e Magazzino.
• Ho creato un utente impostandolo come See Own Leads
• ho messo l'utente nel gruppo "Properties on lines" per avere il form che si apre invece di scrivere subito nell'elenco delle linee d'ordine.

Ho provato a creare un ordine di vendita come utente

La linea d'ordine era senza prodotto, perché era solo un preventivo. Ho salvato l'ordine regolarmente.

Poi ho rivisto l'ordine di vendita andando a impostare un vero prodotto, selezionandolo tra quelli che l'amministratore aveva creato a sistema. Quando salvo, il sistema crasha, perché mi dice che non posso scrivere sulla classe product.product!!!





A qualcuno è capitato? Perché mai avviene una scrittura sul prodotto? Io voglio solo selezionarlo nella linea d'ordine. E' quella che voglio scrivere.

Spero qualcuno mi sappia delucidare.
Grazie in anticipo!

il log del server che dice? non mi è mai capitato

ho solo installato sale e warehouse, ho creato un utente See Own Leads e gli ho messo la spunta su Properties on lines.

Non riesco davvero a capire...

mi sapresti cortesemente indicare come segnalare questo bug al team di sviluppo?
grazie
