Activation context is only present in Tapestry 5 I think. I am using
Tapestry 4.
So I tried persisting getUsers() method but I am getting this error. Am I
missing something?
-----------------------------------------------------------------------------------------------------------
@Persist
public abstract List getUsers();
-----------------------------------------------------------------------------------------------------------
[ +/- ] Exception: Error: Change to persistent property users of
phone/AddPhoneUser/searchForm has been ignored. Persistent properties may
only be changed prior to the rendering of the response page.
