Oh yes, and "snuggletex" doesn't work either.

Betreff: Re: [xwiki-users] Latex {cases} command doesn't work in defaultxwiki 2.0
formula macro
Hi Sergiu,
I tried what you said, adding the line "macro.formula.renderer = native" to
WEB-INF/xwiki.properties and saving it. Then I restarted Xwiki but it didn't work. It
still rendered the formula in a single line. Then I tried "macro.formula.renderer =
mathtran", saved it, and restarted xwiki. It still didn't work. Is there some
part of the the TeX package still missing? I just installed XWiki Enterprise 2.0.3.24848,
it runs on postgres.
I was a little surprised that I had to add a line in the WEB-INF/xwiki.properties file and
not uncomment a line and change its value, as you do in most cases. Could it be that I
have an older config file or is the line in WEB-INF/xwiki.properties not available yet in
the newest version? I used the config from the download, and changed only those values
that pertained to my earlier system settings.
Greetings,
Steven Calkins

Dear all,
The LaTeX {case} macro doesn't seem to work in Xwiki 2.0 with the
default LaTeX renderer.
Try these two examples to reproduce it and compare with
http://en.wikipedia.org/wiki/Math_markup#Examples_2:
[XWIKI CODE STARTS HERE]
=== Continuation and cases===
This example from wikipedia doesn't seem to work:
{{formula fontSize="normal"}}f(x) = \begin{cases}1& \mbox{-1 \le x<
0\par} \\
\frac{1}{2} \;\;\;& \mbox{x = 0\par} \\ 1 - x^2&
\mbox{otherwise\par}\end{cases}{{/formula}}
===Case definitions===
{{formula fontSize="normal"}}f(n) = \begin{cases} n/2,& \mbox{if }
n\mbox{ is even} \\ 3n+1,& \mbox{if } n\mbox{ is odd}
\end{cases}{{/formula}}
[XWIKI CODE ENDS HERE]
Any suggestions?
The cases environment is not standard TeX, it belongs to the amsmath package. This means
that it is not supposed to work using the default backend. It should work with the native
one, which uses the amsmath package, and you could try using the mathtran one. If you
decide to change the backend, you'll find instructions in the last paragraph on
http://code.xwiki.org/xwiki/bin/view/Macros/FormulaMacro#HTechnicalinformat…
