Hi Andreas. So, it will work in production no problem because I use
Tomcat and I can set the serverName and serverPort to return values that
match the fronting proxy server so the domain and port will be the same.
In development, however, I'm using JettyLauncher which doesn't appear to
have that capability, so I'm currently mucking around in the internals
of Tacos and Tapestry to try and hardcode the ajax url during
development (or override the proper Tapestry configuration point if it
exists).

So, did you get the AjaxDirectLink working?

Thanks Jesse. Firebug is great and immediately showed that, in fact,
under the covers, port numbers were getting included and hence the
reason for the error.
Sincerely,

To be really honest I've never run into this issue before. You can do
cross domain scripting now, just not in the way that you are doing it.
I'm not completely sure, but if you go to the source - ie the dojo
users mailing list ( http://dojotoolit.org) - you might find an answer.
An easier method of debugging would be to install the FireBug FF
extension. It will allow you to turn on viewing XMLHTTP traffic at
which point you can see if it looks like you really are trying to
cross domains with script calls. That's the first thing I would do.

Hi All. This is my first time using Tacos or doing ajax stuff,
so if
this is a silly question, please bear with me. I'm trying to do a
very
simple thing, have a Tacos AjaxDirectLink send a request to the
server
and just update some text in my page with the server's response
i.e.:
<a jwcid="@tacos:AjaxDirectLink"
listener="listener:updateMessageWithName"
parameters="ognl:{currentNode.name }"
updateComponents="ognl:{'message'}">some text</a>
Nothing too outlandish, I would think. It doesn't appear that my
request even makes it to the server, however. When I turn on Dojo's
debugging, I'm getting this message:
"DEBUG: ERROR: On line 0 of document : uncaught exception:
Permission
denied to call method XMLHttpRequest.open"
This error message is detailed here --
http://www.mozilla.org/projects/security/components/same-origin.html
--
but the basic idea is you can't do cross-domain scripting. Now, I'm
just using the tacos AjaxDirectLink component, so I'm not explicitly
attempting to cross-domain script things. I *am* running apache in
front of Tomcat, so maybe that is causing me grief (it says
something
about how it has to be the same port number, but all of my URLs
look the
same -- no port #s --, I'm just doing URL rewriting via
mod_rewrite).
Any ideas about how to go about debugging this? It is completely
stopping any work I might hope to do with Tacos.
TIA,
Danny Mandel
