Don't get it
I have set this variable to true and false. Both ways, I get "Historical data can not be displayed in a Factbox" when I edit a page and nothing at all when I create it.
I am still not sure I have managed to communicate what I try to achieve. I want the factbox to be displayed in the bottom of the page after I press the "Show preview" button (action=submit
), based only on the parsed wikitext, without the page's even needing to exist ($smwgShowFactboxEdit = SMW_FACTBOX_NONEMPTY
did it, I presume), just as it was in SMW 1.8.
Anyway, I look at http://semantic-mediawiki.org/doc/Factbox_8php_source.html, line 244, and see that the message about historical data is shown every time there is an oldid in POST or GET parametres, regardless of any configuration settings. This makes clear why there is a message "Historical...' but not why there is no factbox.
