leftover "removed" fields make trouble for client-side validation

[hzamani]

if we remove .fields the _destroy input will be removed and no destruction will happen.
I don't know replacing with _destroy is good or not, but simply setting the hidden filed values to empty may work,
just after $(this).closest('.fields').hide(); add this:
$(this).closest('.fields').find(":input:hidden").each(function() { $(this).val(""); });

It seems like that has the reverse of the desired effect: It nullifies the _destroy input (so the item won't be deleted), but leaves the other fields intact (so client_side_validations will flag invalid input, even though it's supposed to be deleted).

I made a mistake here, and you are right. I don't think there is a reason by not to remove that elements, because there is no way to access fields after hiding them (at least for now). And for this problem it's enough (and also more easy) to only remove the inputs from form and hide the rest, by putting:

`````` $(this).closest('.fields').find(":input:visible").remove();before$(this).closest('.fields').hide();```.

You could use javascript events to perform any custom actions when fields are either added or removed.
