The question is: does this Modalbox send a request via XmlHttpRequest? And does it use Tapestry's handling of the JSON response?
The error you are getting appears to be because it's not recognized as an XHR request, i.e., not an Ajax request and is being treated as a traditional request, for which a Block is not an appropriate navigation result from a event handler method. I'm not familiar with Modalbox so I can't say any more. On Sat, Mar 29, 2008 at 9:55 PM, petros <[EMAIL PROTECTED]> wrote: > > I found what is causing the error.
