jquery's ajax not working in facebook apps

Hi,

I am trying to create a facebook application, all is working fine except the ajax part that I am using to populate a second box from the item selected in first select box.

I am using jquery (v1.3.2) for accomplishing this. This ajax is working absolutely fine on the host where I have taken space for it, but it is not working in facebook.

Here are my questions regarding to this problem,

  • does canvas page url needs to be same as that of my application name. ( in my case it is different)

I am getting this error on the onchange event of parent select box inside facebook.

Access to restricted URI denied" code: "1012

  • what might be wrong...? Please help me solve this problem.

Thanks
