I'd say that this is a bug in the tree controller. Tapestry "should
not" be sending back any JSON data enclosed with "()".
This represents a browser "quirck" and should be handled in the
appropriate place - the browser. I'd bring it up with dojo, probably
by filing a bug in http://trac.dojotoolkit.org .
A mimetype of text/javascript means you are expecting javascript
content such as "function foo(){} " - json mimetype is for object
structures that need to be evaluated in line. Either the tree is
incorrectly using javascript mimetype when it should be using json or
you aren't returning what the tree is expecting.

Some good news.
In TreeLoadingControllerV3.js , runRpc , the mimetype is set as
"text/javascript".
In method doLoad from BrowserIO.js :
- if mimetype is "text/javascript" the method dj_eval(http.responseText);
is called
- if mimetype is "*/json" the method dj_eval("("+http.responseText+")"); is
called
So that's why the brackets are not added and must be set from the server..
A suggestion of how should i go on ?
Should i build a custom ReponseBuilder that treats the text/javascript
mimetype ? Would be beter to be in the framework.. ?
