Changing the state of a document

Hello everybody,

I'm trying to change by hand the state of a document of my
portal_catalog.

I have been searching and i found this:

workflow.doActionFor(object, 'new_state')

but it returns an error: *** Unauthorized: You are not allowed to access
'toNone' in this context

Why? there are any other way to change the state of a document?

Thanks.
