I have written an extension for embedding Google Waves on a wiki page: http://www.mediawiki.org/wiki/Extension:GoogleWave In one of my test wikis this is working like a charm: http://mickenordin.se/~micke/phase3/index.php/Huvudsida on another it is not: http://mickenordin.se/wiki/Wave On the problem wiki it looks like the javascript isn't loaded properly and I need to use &action=purge to get the javascript to load at all. Same problem occurs in a vanilla install of 1.16alpha (r57355) Why is this do you think? What can I do to get the javascript to get loaded on each page view? /Micke
