Perhaps I misunderstand your problem - are you trying to return a Link
from an Ajax event handler?
If Ajax is not involved then this might help:

I am having trouble understanding your answer: are you saying if I
move to 5.0.16 the feature will work? Are you also saying that the
documentation reflects 5.0.16 and not the stable release? Having
read the release notes you link to I can't see a mention of this new
feature.
Righto...so I guess I can go to 5.0.16 and try again.
Thanks and have a good weekend

The docs on the website reflect the latest stable release except for
when a new release is being voted, as is the case currently. The
functionality you're having trouble with is part of 5.0.16.
We are very good about every change being committed against a JIRA
issue, so the release notes:
http://tapestry.apache.org/tapestry5/release-notes.html
Are a very good guide to figuring out what feature went in when.

What version of Tapestry are you using?

Hi,
So the documentation here
http://tapestry.apache.org/tapestry5/guide/ajax.html says:-
"Event Handler Return Types
In a traditional request, the return value of an event handler
method
is
used to determine which page will render a complete response, and a
redirect is sent to the client to render the new page (as a new
request).
With a Zone update, the return value is used to render a partial
response within the same request.
This return value should be an injected component or block. The
value
will be rendered, and that markup will be used on the client side to
update the Zone's <div>.
An event handler may return a Link
<http://tapestry.apache.org/tapestry5/apidocs/org/apache/tapestry5/Link
.
html> and the client will be redirected to that link.
Returning a page name (as a String), or a page class, or a page
instance
will also send a redirect to the indicated page.
"
But my method that returns a Link says throws this exception
Caused by: java.lang.RuntimeException: A component event handler
method
returned the value http://localhost:8080/home/ Return type
org.apache.tapestry5.internal.services.LinkImpl can not be handled.
Configured return types are org.apache.tapestry5.StreamResponse,
org.apache.tapestry5.json.JSONArray,
org.apache.tapestry5.json.JSONObject,
org.apache.tapestry5.runtime.Component,
org.apache.tapestry5.runtime.RenderCommand.
The documentation and the exception seem to be mutually exclusive,
or
is
there a 3rd way I am missing? Any ideas appreciated as it has been a
pretty unedifying afternoon of head against T5 brick walling.
Cheers
Russell
