Thanks for your response, it was something that I thougth, I have to
pass to the form the information that the user is paginating. But i
can't find documentation on how to pass attributes to the form when it's
for paginating and sorting, or if there are specials attributes which
indicates that's the user make a sort or go to next pagnined page.
Also how can I pass a such information only for paginating and sorting?
I mean how to add attributes to the form ? because I tried to make a
such thing : form="${namespace}AddAud?navigate=true" at the place of
form="${namespace}AddAud", but it doesn't pass the attribute correctly
and the form isn't more recognized...
Thanks
Julien
