I have a problem getting the D3js example
<http://extensions.xwiki.org/xwiki/bin/view/Extension/D3+Example> to work.
I have a fresh XWiki 5.4 running. I have installed the D3js with the EM. I
then created a new Space called "D3". I created a page called
"D3.Data" and
pasted the data from the example. I then edited the "D3.WebHome" and pasted
the code to display the graph.
But when I click "Save & View", I only get a blank page. F5 (refresh) does
nothing. I then edit the page in the WYSIWYG editor...I can see the graph
being displayed! I can even use the arrow keys left and right to interact
with the graph. But when I hit "Save & View", the graph is NOT being
displayed, but part of the velocity code is. If I edit the page in XWiki
mode, I can see that some velocity code is now being 'escaped' by XWiki.
What am I missing here????
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.
