[jQuery] validate plugin and CodeIgniter

hi
i'm giving a go at codeIgniter using jquery for the js side.
So i got a form which i validate with the validate plugin but in CI
when i submit the form the js starts a loop and i must shut down the
browser.
I read somewhere that it could be because the validate plugin use the
GET method by default which CI refuse to accept.
Is this true?
Anyone has used this two togheter?
Thanks Vitto
