That's the whole point: in the wrapModel, I store a key with which I can retrieve the wrappedModel from a context. So the wrapModel only stores a 'transient' reference to the wrappedModel, and its detach() clears that reference. Whenever asked for, the wrapModel can retrieve the wrappedModel from the context by key. The reference is only needed to improve retrieval for the current requestCycle. -- View this message in context: http://www.nabble.com/NPE-in-Component.detachModel%28%29-when-wrappedModel-is-null-tf4048326.html#a11505093 Sent from the Wicket - Dev mailing list archive at Nabble.com.
