remove answer (default body field) in FAQ + CCK

Hi,

Thank you for this great module.

I wonder how to remove the answer field (default body field) and replace it with several cck fields. (why do I need this ? I have a FAQ with 3 answer types, always mandatory, I use those separately in views lists afterwards - I will use dates or number fields as well later on)

I tried "To omit the body field for this content type, remove any text and leave this field blank."
It nearly worked, in manage fields the answer field disappeared.
But when I create or edit a FAQ the title of the body field has disappeared, but not the textfield. Perhaps, because I use FCKeditor BTW.

As a result, I have to disable rich text, remove the

automatically created by FCKeditor, each time I create or edit an FAQ. And submit. It works. That's fine for me but not for an end-user.

The funny thing is that I was about to step back and use the default answer field again, but it doesn't accept any other content but blank. In other words whatever I type (if I don't erase all) in the answer field yet, I get a blank error message on submit. That's weird.
To reproduce this behaviour, enable FCKeditor (filtered or full HTML). Delete the label of the answer field. Save. Then rename it. Save. Create a new FAQ. Not sure if you need to add a few CCK fields to the FAQ form.

I tried to erase all the former faq I created but that doesn't help, the problem is still there.
