Poll : ahah and validation creates problem

Hi,

I found a bug when creating or editing a poll node

Steps to generate that bug ::

a) Goto node/add/poll
b) Click on Add another choice button without filling any form values, so validations are fired
c) Now click on save button 2 times
d) you can see the following error on poll/js path

{ "status": true, "data": "\x3cdiv class=\"messages error\"\x3e\n \x3cul\x3e\n
\x3cli\x3eQuestion field is required.\x3c/li\x3e\n \x3cli\x3eYou must fill in
at least two choices.\x3c/li\x3e\n \x3c/ul\x3e\n\x3c/div\x3e\n\x3ctable

\x3c/tr\x3e\n\x3c/tbody\x3e\n\x3c/table\x3e\n" }

Well, poll/js is ahah path of "Add another choice" button then why it's called
when we click on "Save" button

Please solve it asap or if anybody has any quick solution to overcome it then
please reply (it's too urgent)

Thanks
