The local sitemap is now stale; even though the sitemap on the server now reflects the change the local sitemap does not.
What we should do is fire an event like 'create' when the button gets clicked and then catch it in the neighborhood and add the page to the local sitemap. github
When you create a new page on a wiki or edit the first paragraph (which creates the synopsis of the page) then the synopsis SHOULD be inserted into the wiki-client's version of sitemap.
