This is cool!
> Simplify connecting a link or form to an (enclosing) Zone

> Key: TAP5-1295
> URL: https://issues.apache.org/jira/browse/TAP5-1295
> Project: Tapestry 5
> Issue Type: Improvement
> Components: tapestry-core
> Affects Versions: 5.2.2
> Reporter: Howard M. Lewis Ship
> Assignee: Howard M. Lewis Ship
> Priority: Minor
> Fix For: 5.2.2
>
>
> Currently, when connecting a link to a zone, you bind the zone parameter of
> the link to the client-side id of the Zone.
> To do this, you must know the client-side id of the Zone.
> It would be nice if the zone value could be evaluated on the client and make
> use of the rendered DOM to simplify this.
> I thought the special string "^" could mean "the containing Zone", and could
> be located via the "t-zone" CSS class that Zones normally have.
> An extended form could be "^.foo" to find an enclosing element with CSS class
> foo and assume that is the zone (this would help when dealing with nested
> zones).
> The exact syntax is up for debate but the idea is that the connection could
> be made on the client-side without having to deal with the (relative)
> intricacies of either assigning a zone id explicitly, or reading the Zone's
> id.
