Hello,
Just one little remark: the word "secret" makes no sense in this context because we are dealing with open-source software. If someone wants to know in detail how gvSIG or any of its dependencies work, then the source code is right there, waiting for you. No "black boxes" here.
Let us hope Benjamin's message was not some kind of innuendo ;-)
Regards,
Juan Lucas Domínguez Rubio

See, that's what I call a dark secret.
Thanks, people, for all these suggestions.
Surely, one of them must trick that parser
into accepting my simple filter statement.
Cheers,
Ben
