OMG! Anthony you really rock man!!
Thanks **a lot**
That's exactly what's going on, and it explains the error being so sporadic.
Definitely, I'll transform the request.get_vars before passing it to URL()
in order to avoid the error.
May I ask how did you figure out? I mean, did you already know about that
jquery stuff, or did you made some search with the parameter's names?
Anyway, good one, I really apreciate your help, as always!
P/D: I looked in the web2py's website and I didn't found any way to donate.
I've seen an old post saying that it was better to donate to them who
needed it most, the post gives a link to donate to another cause. But we
(our company) would really like to contribute, not only to web2py, but also
to you (that small group of people who is always here helping).
