> 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
> Assignee: Howard M. Lewis Ship
> Fix For: 5.4
>
>
> 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.
