CodeRef macro not working in wiki

edit

http://wiki.ros.org/tf/Tutorials/Writ... So on this page, the CodeRef macro didn't work, and I've even tried to copy-paste the corresponding section in

http://wiki.ros.org/WritingTutorials#...

==== CodeRef ====
In a tutorial, you want to reference a code block that you have created earlier in the tutorial you can use `CodeRef`. 
{{{start
{{{
#!cplusplus block=blockname
code....
is super 
and awesome
}}}
start}}}

You can then use the `CodeRef` macro to refer to it
{{{
<<CodeRef(blockname,1,2)>>
}}}

This then looks like:

<<CodeRef(blockname,1,2)>>

the exact same section which works on the "writing tutorials" page didn't work on "writing a tf listener" page.
