RESULT - page redraws. foo0 = 'A > VALIDATED'. foo1 is empty. SUCCESS! > 3. foo0 is empty, foo1 = 'A'. click submit. RESULT - page redraws. foo0 is > empty. foo1 = 'A'. FAIL! - foo1 should say 'A VALIDATED' > > For some reason MyAction.setFoo1() is being invoked *again* after I set foo1 > to 'A VALIDATED' in my validate() code. Why is that happening? I know it has > something to do with the Languages control that appears before the foo1 text > field, because when I remove the Languages control everything works as > expected. > > Anyone have any ideas about what the Languages control is doing that is > causing my foo1 field to get reset to the original submit value?
