hi kalle, i've tried to solve this with another indirection :).
i encapsulate all conversation specific data in a ConversationContext object. if i want to invalidate a conversation i just remove this context. i'm going to send you a zip with my experimental project to your gmail address. maybe it helps. g, kris Kalle Korhonen <kalle.o.korho...@gmail.com> 19.01.2009 06:36 Bitte antworten an "Tapestry users" <users@tapestry.apache.org> An Tapestry users <users@tapestry.apache.org> Kopie Thema Discard persistent field changes for one strategy only? I would like to discard all changes for one strategy only. PersistentFieldManager always iterates over all strategies when calling discardChanges() and I don't see any (easy) way to decorate the PersistentFieldManager to allow it to discard selectively for some strategies only. Would it be possible to add a discardChanges(String strategyName, String pageName) operation to PersistentFieldManager or to make the getStrategy(String strategyName) public? Or is there any other way to get a hold of a strategy in a service that the strategies haven't been contributed for if I know the type? This functionality would be needed for conversational scope implementation. At least in my mind it makes perfect sense to allow this, I'll open an issue if somebody agrees. For now, I can make it work by contributing the same ConversationPersistentFieldStrategy to another service in addition to PersistentFieldManager in my AppModule, but I can't make it "plugn'n'play" without the "selective discard" functionality.
