In my example, I showed the fieldnames at the end printed twice, so as to include them twice in the replacement string (once as a hidden value, once in the table cell). I guess this is some form of printf, so that should be valid.

If not, and you're tied down to the implementation of this using the interface described (as opposed to writing a script that reads the results of your 'findbug' progam into a bunch of variables), then you'll need to find some other way of passing / displaying the fields at the same time - maybe as a (non-editable?) text-box or something.

Cheers, Ben.
