I'm developing a XForms front-end to create a METS manifest.

>    4.       <file ID="" MIMETYPE="">
>    5.         <FContent>
>    6.           <binData xsi:type="xsd:base64Binary"/>
>    7.         </FContent>
>    8.       </file>

> My problem is that when someone put the value in the xform:upload i need
to update the three colored places. I'm ok with the green parts but the red
part I simply have no clue how to do it. When you choose a file and the
category of that file, the file should be stored in binData (achieved), the
ID and MIMETYPE should be updated (achieved) and a new fptr with the FILEID
should be created in the div of the specified category (this is what I don't
have a clue on how to do).

the form is synchronized with the model if I go that way?

Thanks so much for the help,
