>                 URL: https://issues.apache.org/jira/browse/TAP5-1449
>             Project: Tapestry 5
>          Issue Type: Bug
>          Components: tapestry-core
>    Affects Versions: 5.1.0.5
>            Reporter: Geoff Callender

> Eg. In an event handler method I create a Link, add a query parameter to it called "thing" with value "%ab", then return the link. The resulting URL is something like this:
>     http://localhost/myapp/mypage?thing=%ab
> but it should be:
>     http://localhost/myapp/mypage?thing=%25ab
> In mypage, when we do this:
>     value = request.getParameter("thing");
> the value is null from the first URL, which is bad, and "%ab" from the second URL, which is good.
> So Tapestry is correctly decoding "%25" to "%", but it is not encoding "%" to "%25".
> For now, the workaround is to do this when adding the query parameter:
>     link.addParameter("thing", value.replaceAll("%", "%25"));
