[Mediawiki-l] mediawiki 1.5.2 editting problem {{Portal|{{{topic}}} }}

Sun Nov 13 05:09:42 UTC 2005

Hi Rowan,
Thanks again for your detailed explaination.

I do have a better understanding of Namespace and
subpage now.

But I still have one problem.

As I explained earlier that I am running mediawiki
1.5.2 on a Fedora Core 4 box.

I have PHP-5.0.4-10.5 with Zend PHP optimizer
installed.

Currently the my mediawiki system does not seem to
interpret {{/box-header|{{{topic}}}
portal|Portal:{{{topic}}}/Intro|}}  
It interpret the above as      
Template:/box-header}portal|Portal:{{{topic}}}/Intro|}}

My system seems does not understand {{{topic}}} when
{{{topic}}} is inside {{Portal|}}}

Is this a bug or I am missing something

Thanks 
jc
