    Resolution: Invalid

Starting in 5.2.0, there's new client-side options for Zones to send arbitrary parameters as part of the request, and a @QueryParameter annotation that can be used on the server side to get that same information.

> A Tapestry.js hook into the parameters of event and action links would be very useful in order to create more powerful client side controls. As of now, I'm using  a function created by equanda that performs string transformations on a generated link. It works, but it would be so much cleaner and safer with a built-in function looking something like this:
> Tapestry.addEventLinkContextValue(link, value) {
>   link = link + '/' + value;
> }
> This is of course a simplified example that probably wouldn't work... :)
> Here are some use cases to make it clearer why I want this feature:
> 1. A dropdown that updates a zone through its onchange event, pushing the selected value into the context of the trigger link.
> 2. A textfield that works like an autocompleter on a connected zone. Same pattern, the entered text is pushed into the context of the trigger link.
