Another option is to make the name attribute optional
in the view directive:

    <xmlrpc:view
        for=".IPoll"
        allowed_attributes="summary detail"
        permission="MrPoll.ManagePolls"
        class=".PollStatistics"
        />

This would look better if it was:

    <xmlrpc:view
        for=".IPoll"
        methods="summary detail"
        permission="MrPoll.ManagePolls"
        class=".PollStatistics"
        />

This works for me.
