I've got round this now but im not sure if its a clean way...
Instead of observing one field i observe the whole form and have added
a checkbox.
I populate the hidden field with the form date and force a .click() on
the check box which triggers the ajax and i get my results.
Does anyone know a better way of triggering ajax from javascript
rather than through php $ajax->observeForm?
Cheers,
Chris
