Solution for consistent checkbox handling

Hi All,

A recent post asked how you get around null-values for unchecked checkboxes.
Although there are many ways around it, sometimes the behaviour is really
inconvenient. Picture for instance a page where a checkbox is sometimes
suppressed based on the user's rights -- you don't know whether the control
was absent or whether it was unchecked.

Now picture the following HTML to get around the problem:

<input type="checkbox" name="isAssignable" value="1">
<input type="hidden" name="isAssignable"< value="0">

request.getParameter("isAssignable") in my environment works properly, in
other words I ignore "isAssignable" when null and I update it as a flag if
it is not null.

Can anybody see a portability problem or any issues with this approach?

Thanks
Bob
