I'm developing a gadget with atlassian development kit with a local jira instance, (v5.1.8#787-sha1:823790c).
I include several javascript libraries, which I have defined in my atlassian-plugin.xml:

</web-resource>

My gadget makes two AJAX REST calls: One that requests html template for the view, and one that requests data to display in a table.
In my local running jira, my gadget is running fine, but when I deploy it to our production jira, after the second ajax call, the one who requests data for a table, I get the following javascript error messages:

In Chrome: "Uncaught TypeError: Cannot read property 'length' of undefined" in file "com.atlassian.auiplugin:jquery-lib.js:2"

In Firefox: "TypeError: a is undefined
..."resolve"],fail:[b,"reject"],progress:[c,"notify"]},function(a,b){var c=b[0],e=b..." also in file "com.atlassian.auiplugin:jquery-lib.js:2"

I used a File diff tool and found only one big difference: In the production gadget.xml, my js-resources were packed into one file, called "[...]/download/batch/mygadget:resources/mygadget:resources.js"
But in my local jira the resources were loaded separately.

Can this be the reason for the exception?
Thanks in advance
