I've got a bean with a list of sub-objects. In general the interactions
between the bean and the pages works correctly, except when an entry is
empty. In that case, the property binder removes the parameter and it's
never cleared.
That is, I've got inputs with names like "whatever[0]", "whatever[1]",
"whatever[2]", etc. When the form posts, and the user has cleared the
input for "whatever[1]", then the browser submits correctly with an empty
value for that parameter. However, in the routine "validateRequiredFields",
the parameter is removed because, well, I'm not sure why. There's a
comment (around line 530 in my 1.5.3 version of the code) in the
DefaultActionBeanPropertyBinder that says it wants to remove the parameter
so as not to cause validation problems later on. That breaks things for me
- it means that nothing can ever tell that the field should be emptied.
Is that a bug that's been fixed, or am I just doing something wrong?
