Two mailforms on a page cause error on field validation
Recently I had a complaint by a customer who had set some fields in a standard mailform to "required" but evaluation failed and the mail was sent without having been evaluated.
As Ernesto Baschny pointed out, this is due to a default TS setting in css_styled_content:
tt_content.mailform.20.formName = mailform
Ernesto suggested the following:
"An easy solution would be to default the provided TS to the "hash-based" id for forms..."
