Hi, I'm decorating the RequestExceptionHandler in order to handle exceptions and then redirecting to the previous page (the one I find in the "Referer" HTTP header).
This works fine for normal page requests but I would like to handle also the case of Ajax requests. The JavaDoc of RequestExceptionHandler.handleRequestException (http://tapestry.apache.org/tapestry5/apidocs/org/apache/tapestry5/services/RequestExceptionHandler.html) says: "The handler is also responsible for setting the response status and the X-Tapestry-ErrorMessage response header. These are very important in Ajax requests to allow the client-side logic to detect the error and present it to the user." I couldn't find documentation to figure out to what values I should set the response status and the X-Tapestry-ErrorMessage response header. Does anyone have suggestions ? Thanks in advance.
