limited number of XIDs??

Hi I was wondering whether there is a limited number of XIDs that can be generated in a short period of time? I am working on an ajax and jquery based member management system whereby members can be created and edited quickly without having to redirect, etc. For the most part this is working great, but I can only seem to generate a new XID once, and then I have to refresh the page completely, which sort of voids the point of the entire development really.

Any ideas?

I am just changing the XID value in my member add form using the following code: $(‘input[name=”XID”]’).val(“{XID_HASH}”);

This changes the value, but only once and then if I run that same line of code again after creating another member it doesn’t seem to execute.
