Well, I can't just create a new object, since I was editing an existing one. So I had my object persisted, but now it is gone and I'm getting an NPE. Tapestry doesn't seem to know my application requires the session (and present a session timeout page) and I haven't found a way to tell it to stop processing the FORM submission yet.
I'll look at your conversations link and see if that gives me ideas. mrg On Thu, Sep 17, 2009 at 5:33 PM, Kalle Korhonen <kalle.o.korho...@gmail.com> wrote: > Just to prevent nullpointers, in your onActivate() you should have if > (object == null) object = new Object().
