First thing you are missing is that the extension on the page is just a demo for the impatient to view something before even installing something. It fetched the javascript stuff from the D3 website directly; no need to install the D3js extension to run it ;) Then, indeed the WYSIWYG editor does not handle the code snippet gracefully, just opening the editor and saving without editing breaks the thing, there is just too many inline <script> and other not-best-practice stuff in it it goes crazy and damages the thing. Using the Wiki-editor is highly recommended for this beast ;) But these are all side notes .... What is really puzzeling and what I am starting at for an hour without understanding is that the normal view does not show anything. All I get is a JavaScript Error "Refercence d3 not defined". If you look at it in "plain view" it should be ok (same as inside the WYSIWYG editor frame): http://localhost:8080/xwiki/bin/view/D3/WebHome?xpage=plain It seems one of the libraries XWiki loads in its normal layout conflicts with d3 in some way. (Installing and using the extension "as advertized" does not work either, as the "d3:loaded" event is never fired, btw ..) Well, that's as far as I got. Only tested with Firefox, however. Maybe someone else can shed some more light on this. Clemens _______________________________________________ users mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/users
