yes - that's because the response was not served by the appropriate
service (it should have been PartialService, but it wasnt)... if you
are already using a patched version of Tapestry, and you have some
enthusiasm, please try the following:
modify tapestry's Form.java, and make private ILink
getLink(IRequestCycle cycle, String actionId) a protected method...
override in tacos PartialForm.java like this:
protected ILink getLink(IRequestCycle cycle, String actionId) {
IEngine engine = cycle.getEngine();
IEngineService service = engine.getService(PartialService.SERVICE_NAME);
return service.getLink(cycle, this, new String[] { actionId });
}
after these changes, verify that the hidden field "service" in your
Forms starts with "partial/..." - i think something like this should
to the trick.
i found that monitoring the http traffic with something like tcpdump,
packetyzer or the charles http proxy is really helpful in diagnosing
xmlhttprequest-based apps.
