                 Key: TAP5-1744
                 URL: https://issues.apache.org/jira/browse/TAP5-1744
             Project: Tapestry 5
          Issue Type: Bug
          Components: tapestry-core
    Affects Versions: 5.3, 5.4, 5.2
            Reporter: Howard M. Lewis Ship


At the time the event is triggered, the FormSupport (and other stuff) is in the Environment. The new page render occurs INSIDE the same environment, causing errors when the new render of the Form tries to store its own FormSupport into the Environment.

The solution is to use Environment.cloak() and decloak() around the new render.
