I've written an extention, but I'm having trouble with inputs not being saved.

Hi guys,

I've written a plugin that dynamically populates fields (select, checkbox, radio) with options determined by the choice that the user has selected from a previous input. It works fine, unless the input is on the last page of a multiple page form, in which case the option selected by the user is no longer saved.

Does any body know why this may be?

Thanks in advance.

The code that we've created can be viewed here:
PHP: http://www.pastie.org/private/vbxwwn8da3rbfag9mw3zg
(This is just part of a bigger class we've written, but it's the bit that handles these functions)

JS: http://www.pastie.org/private/mk5pqaewfshu2stjeazzcw

The issue exists on Checkboxes, Select boxes and Radio buttons but not Multiselect boxes.

The idea is that using Ajax, the Checkboxes / Select / Radio / Multiselect options are dynamically populated based on a previously selected value in a "higher" input.

The population of options of the options occurs, but for any inputs other than Multiselect, the values are not posted to the next page when the page changes.

This only occurs we are using a PAGED form, and the inputs are not on the last page of the form.

Any insight as to which functions / hooks are triggered on a page change are welcome -- we're at a loss to see what we've done incorrectly (given that multiselect works!)
