Hi,

I have a problem. I want to use transformer, it gets XSL stylesheets not from 
filesystem, but from database. As some good mind advised, I used cocoon:/ 
protocol to call another pipeline with databasereader, which returns 
appropriate XSL stylesheet. But cocoon reports: "Streaming of an internal 
pipeline is not possible with a reader."

Source fragment of sitemap is here:


<map:match pattern="*/html/*/*/*.html">
 <map:generate type="serverpages" src="logic/main.xsp">
 <map:parameter name="language" value="{2}"/>
 <map:parameter name="format" value="html"/>
 <map:parameter name="subweb" value="{1}"/>
 <map:parameter name="id" value="{4}"/>
 <map:parameter name="content" value="{3}"/>
</map:generate>
<map:transform src="cocoon:/{1}/html/{2}/stylesheet/0"/>
<map:serialize type="html"/>
</map:match>


reader:
-------

<map:match pattern="*/*/*/stylesheet/*">
<map:read type="databasereader" src="{1}" mime-type="text/xml">
 <map:parameter name="table" value="subweb s, article a, article_version v, 
article_version_format avf, format f, language l"/>
 <map:parameter name="image" value="v.body"/>
 <map:parameter name="key" value="s.name"/>
 <map:parameter name="where" value="s.stylesheet=a.id and a.id=v.article and 
v.id=avf.article_version and avf.format=f.id and f.name='{2}' and 
v.language=l.id and l.name='{3}'"/>
</map:read>
</map:match>


What I'm doing wrong? Thanks for answer!
