      Bug process :

      • Write a component using ajax form and a <t:body />. When form is submitted in ajax, the component renders its body.
      • Start jetty, open the page
      • Restart jetty, submit the ajax form
        -> The form is refreshed without the body of the component

      Attached to the ticket, a little project showing the problem (just open the index page and click submit)

      The problem is in ComponentPageElementImpl, the beforeRenderBodyPhase should be called for the part of Index template inside my component, but as the page has never been rendered before, beforeRenderBodyPhase is null.

      We have the same issue if a new page instance is created to treat the ajax request. If the page is taken from the page pool, then there is no problem as the page has already been initialized.

      A patch that could fix it (didn't test it) :
