Re: [Semediawiki-user] String value from custom parser tag extension, not understood by SMW

[Samuel L. <sam...@gm...>]

Hi Yaron and others,

I finally found the solution now to this old problem of mine!

It turns "Tag extensions" [1] don't work together with "parsy" stuff 
like templates and semantic facts, and that one should create a "Parser 
function extension" [2] instead! :-o

So, after I did this, in the following commit, it works!:

[2] http://www.mediawiki.org/wiki/Manual:Parser_functions

Cheers
// Samuel
