Percent (%) symbol in query parameters is not being encoded
------------------------------------------------------------
Key: TAP5-1449
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"));
