Dear All,
I discovered my issue using a step-by-step debugging...
the problem was that in the master "form" I forget the multipart="true" and I
setted this property only in the subform where I use the uploader....
So we can add in "commonMistakes" the fact to put "multipart=true" in the master
form also when it is needed only in one subform...
Cheers
ivan
