When loading data for t:variable/@src fails, nothing happens in browser.

[bruno]

I've noticed this a few times already with Firefox.

If you have a template which loads data using t:variable, and this fail, e.g. because the addressed resource does not exist, then nothing happens in the browser: the current page remains shown, giving the impression that everything that somehow no error happened. Most likely this is only the case when the t:variable is near the top of the template.

Have not looked closer into the origin of the problem, possibly a failure to reset the output, in which case the same problem will likely occur in other occasions as well.

The response Restlet sends to the browser in this case is:

HTTP/1.0 200 The request has succeeded
Content-Type: text/html
Date: Mon, 15 Dec 2008 15:36:50 GMT
Accept-Ranges: bytes
Server: Noelios-Restlet-Engine/1.2.snapshot
Connection: close
Transfer-Encoding: chunked

HTTP/1.0 500 An exception occured writing the response entity
Content-Type: text/html
Date: Mon, 15 Dec 2008 15:36:50 GMT
Accept-Ranges: bytes
Server: Noelios-Restlet-Engine/1.2.snapshot
Connection: close
Transfer-Encoding: chunked

Thus double headers. It seems the first set of response headers was already flushed. Needs further investigation.

I found out the source of the problem, it is a problem in Restlet:
​http://restlet.tigris.org/issues/show_bug.cgi?id=687

The problem was that the Jetty connector was not detected, and hence not used, and the simple default server of Jetty isn't able to reset the response after the initial headers have been written.

Fixed by upgrade to newer restlet snapshot, in r1001.
