Drupal.service() [json_load] not loaded

ciao,

I'm interested in the module, and I'm trying to get it working.

After setting up a test view, I get the collect button but an error occur because Drupal.service function isn't inserted in the js code of the page.

I've inserted a call to json_load() function in theme_collect_nodes_client_js(), and now I get it working.

My doubt is in the two requests to json_server, that in firebug look like

1) system.connect

http://localhost/,/,/,/,/,/,/?q=services/json&api_key=.....&method=syste...

2) collect_nodes_service.request_status_batch

http://localhost/,/,/,/,/,/,/?q=....

the response in both cases is

{ "status": false, "data": "Invalid method " }

It work, but is this the correct way to proceed?
(Yes, I'm not so "in" in service module, I hope to resolve by my self)

Congratulations for your work :)
thanks for help,
luca
