I'll give this a try tomorrow at work (3-day weekend here in Barcelona ...)
But I am curious, why should this be necessary? According to Spring's
'convention over configuration' rules, if I create any type of
FormController that uses a Command object (say MyObjectFormController), it
should use the MyObject Command object by default, correct? That's what I
thought anyway ... But even after hard-wiring it in my applicationContext
file it doesn't seem to like it ...
Anyway, as I said, I'll try your recommendation tomorrow. Many thanks!
