[Mediawiki-l] Pb (parsing?) with <tag param=value> to {{template |param={{{1}}} }} <splist /> and {{#tag:splist}}

Hi tutti, question about #tag or {{{param=}}}

I would like to use SubPageList3 (<splist />), but by the way of a template {{sous-page|1|2}} with parameters, and so I simply call {{sous-pages}} with the good "parent page" with a parameter (named or unamed, I tried both) . And I don't succeed ! (MW1.12 on localhost/WinXP/WAMP2.0)

I believed that {{#tag:MyExtension |param}} would allow to give/transmit parameters to that kind of ExtensionTag, but I probably misunderstood something http://www.mediawiki.org/wiki/Extension:SubPageList3 (I 've read articles about TagParser and new #tag included in MW1.12)

So I defined {{sous-page}} like this : {{ #tag:splist | parent={{{1|{{FULLPAGENAME}} }}} | showparent={{{showparent|no}}} | sort=desc | sortby=title | liststyle=bar | showpath= | kidsonly=yes | debug=0 }}

Apparently this template (this code above) works directly in a test-page and I get the list (so MW seems to understand {{ #tag:splist | parent={{FULLPAGENAME}}..)

But it works not when I call {{Sous-pages | Espace:Nompage}} ... It looks like it doesn't understand {{ #tag:splist | parent={{{1}}}..) The message is :"Sous-pages n'a pas de sous-pages à énumérer."

Please what happens ??

Merci d'avance et bon WEnd à tous ;O) @+ de jfb "0.02$"
