Hi Fabio,

I notice that you are using `xxforms:get-request-parameter()` with the
`xxforms` prefix,  but also have calls to `xxf:instance()` with the `xxf`
prefix. If you really want to do that, you can, but need to make sure you
declare both prefixes. Instead, I'd recommend you use `xxf` in all cases,
and make sure that you have a namespace defined for that prefix
(`xmlns:xxf="…"`) in your `properties-local.xml`.

You'll let me know if this helps.

Alex

Fabio, did you get a chance trying to use the `xxf` prefix everywhere? If so,
did that solve the issue?
