I don't even need to.

In your form you have a field holding a java.lang.Integer object. XML
can only contain text (strings), so this object needs to be converted to
a string. Since it is the binding which takes the value from the form
and puts it in the XML, it is the binding which performs this
conversion, and in order to do so, it uses the convertor specified in
the binding.

In your binding you have:

>     <fb:value id="bignumber" path="bignumber/@value">
>       <fd:convertor datatype="integer"/>
>     </fb:value> 

Properly configuring that binding should solve it. For instance, for
what you want to achieve, you can do:

>     <fb:value id="bignumber" path="bignumber/@value">
>       <fd:convertor datatype="integer" type="plain"/>
>     </fb:value> 

Hope this makes it clear.
