Hi all,

last week me made a migration from XWiki 0.9 to XWiki 1.1.2, and now we re experiencing the next problem.
>From time to time the next exception is thrown :
09:55:24,604 WARN TP-Processor5 http://<server>/xwiki/bin/download/Panels/SyntaxHelp?id=0 XWikiAction:execute:183 - Uncaught exception: Error number 0 in 11: Uncaught exception Wrapped Exception: Index: 0, Size: 0 com.xpn.xwiki.XWikiException: Error number 0 in 11: Uncaught exception Wrapped Exception: Index: 0, Size: 0 at com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:163)

I traced this to the XWiki syntax Help panel that is shown when editing in Wiki mode. The images sub-panel shows the syntax for including images to a wiki page that looks like this :
{image: img.png} img.png{image: img.png|30} img.png {image: img.png| |20} img.png {image: img.png|30|20} img.png

IMHO the img.png in the right column will show img.png modified as shown in the left column : default size, 30 pixels wit=dth, and so.
The code in http://<server>/xwiki/bin/view/Panels/SyntaxHelp that generates each of these lines looks like this :
<img src="$xwiki.getURL("Panels.SyntaxHelp", "download", "id=0")" height="30" alt="img.png"/>

and my guess is that it fails because the img.png file isn't uploaded. Am i right ??
Even if I call the page http://<server>/xwiki/bin/download/Panels/SyntaxHelp from my browser a beautiful "This template dos not exists" error is shown.

have I missed something in the installation process ??

BTW, i tested the same URLs in xwiki.org and the template errors is shown but calling to http://www.xwiki.org/xwiki/bin/download/Panels/SyntaxHelp?id=0 shows me a persons silouette.

Thanks in advance.
