The problem is that #{param.edit} doesn't maintain a constant value.
The component's "rendered" attribute value must be the same between
the first and second request. If it's rendered on the initial
request, but not rendered on the submitting request, then the backing
bean won't be updated (the value won't even be validated).
Components are only evaluated (decoded, converted, validated, copied
to backing beans, rendered) if the rendered attribute is true.
