Cant open modal for leapard input.

[joseym]

I have the following:

@plugin.route('/search')
def search():
    search_string = plugin.leopard(heading='Search by Star')
    if search_string:
        url = plugin.url_for(
            'starVids',
            name=search_string
        )
        plugin.redirect(url)

which is throwing this error:

I guess that would be because, at least on the version I installed within my dev xbmc, 2.4.0, the attribute name is keyboard.

Is the documentation wrong or am I on the wrong version?
