Can you help me with the correct way of obtaining a handle to the main Wiki
?
I mean what am i doing wrong in,
<code>
context = Utils.prepareContext("", request, response, engine);
context.setMode(XWikiContext.MODE_GWT);
context.setDatabase("xwiki");
XWiki xwiki = XWiki.getXWiki(context);
</code>
Anyway, i will look into this.
Thanks a lot.

Hi Thomas,
Sorry for the late reply, i just woke up :)
This is ludovic's original code,
<code>
context = Utils.prepareContext("", request, response, engine);
context.setMode(XWikiContext.MODE_GWT);
context.setDatabase("xwiki");
XWiki xwiki = XWiki.getXWiki(context);
</code>
So yes, Utils.prepareContext() is used but XWiki.getXWiki() fails.
I just committed a throw in Utils.getComponent when component manager
has not been initialized, that way we will be sure it's the problem or
not.
Thanks.
