In this case, I think is *the* solution, because without it, the module
just don't work. 

The problem was that I was missing placing an ExtJSJSONDataFormatter, and a
ExtJSJsonWebdataInputAdaptor, both linked to the TFPWebProviderDataModule's 
ContentProducer and InputAdaptor properties.

It was easy to find it after I noted there was an "wmdebug" define turned
off in sqldbwebdata.pp, I turned it on and compiled. When I'd run the code
again, the Access Violation I was getting was more informative with a 
detailed stacktrace who pointed me to fpwebdata.pp, line 828, where I saw 
the need of a TCustomWebDataInputAdaptor.
