[TYPO3] Two Mailforms on a page - Bug?

[Alexander Schloegl]

Hello list,

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.

I found out that he had two forms on one page, and typo3 (4.0 btw) gives 
them the same id (id=mailform) which causes the JavaScript to fail.

I have succesfully reproduced the error on other installations so I 
think this is a bug.

Before posting it as a bug I am asking the list.

thanks in advance
