Hi all, I have a problem serializing a ValueComposite when I pass it from one page to another in Wicket. Wicket is checking if the properties of the ValueComposite are serializable, and somewhere in the process (that's where I get lost) we have a runtime.value.ValueInstance which is not a Serializable. Since a ValueComposite is Serializable, shouldn't the ValueInstances be so too? Shouldn't Wicket be able to serialize my UserEntityDTO, or am I missing something basic?
I think Niclas was working around this issue in http://old.nabble.com/ValueComposites-are-not-%27type-proxied%27-like-other-Composites.-td22072609.html#a22072609 Thanks for any comments...
