I'm using extjs with jquery and it works fine. But when i submit forms - i get a little problem. The problem is with form serialize function.

if i've text value "just a simple text", after form submit i get "just+a+simple+text". I don't where to post this problem - here or in jquery forums

i get inside jquery and ext-base code and i found this

jquery serialize function, at the end.
Code:
   return s.join("&").replace(/%20/g, "+");
how can i submit form without this '+' and using jquery adapter?

P.S.
i use form.getValues() and Ext.Ajax.request to submit form
