[xwiki-devs] rights to addObject

Is there a right level required to call the method $doc.getURL('objectadd')?

I have a form showed only to user with comment right..
But when they submit this form, if they don't have an admin or maybe 
edit right, they have an error "...not allowed to access this page...".

So how can i call the method $doc.getURL('objectadd') or something that 
would have the same effect but with only comment right?

Thank you
