Get error "Streaming of an internal pipeline is not possible with a
reader". - only occurs at second level of the publication content tree
I have created a pipeline like so:
<map:match pattern="fetchPortfolioList-*">
<map:select type="parameter">
<map:parameter name="parameter-selector-test" value="{1}"/>
<map:when test="portfolio">
<map:generate src="test.xml"/>
<map:transform type="xslt" src="test2html.xsl"/>
</map:when>
<map:otherwise>
<map:generate src="emptytest.xml"/>
</map:otherwise>
</map:select>
<map:serialize type="xml"/>
</map:match>
and am calling it within the aggregator which creates the cmsbody
element like so:
<map:match pattern="lenyabody-raw-*/*/*/*/*/*/**">
<map:aggregate element="cmsbody">
<map:part
src="cocoon://modules/sitetree/menu/{2}/{3}/{5}/{6}/{7}.xml"/>
<map:part
src="cocoon://modules/sitetree/search/{2}/{3}/{5}/{6}/{7}.xml"/>
<map:part
src="cocoon://modules/languageselector/text-none/flagsize-13"/>
<map:part src="cocoon:/document-content/{1}/{2}/{3}/{7}"/>
<map:part src="cocoon:/fetchPortfolioList-{7}"/>
</map:aggregate>
<map:serialize type="xml"/>
</map:match>
(7 will be the path from the lenyabody-raw-*/*/*/*/*/*/** pattern).
I am looking to generate something different for the "portfolio"
section, specifically get a dynamic collection and put it through a
different transform though here I'm just loading test files.
This works fine when I am at the top level of the publication tree,
i.e /[publication]/[area]/[whatever].html
However when I go deeper down the tree e.g
/[publication]/[area]/[[section]/whatever].html I get:
Streaming of an internal pipeline is not possible with a reader.
and the line identified is where I call the serializer directly after
the aggregator.
I'm using a generator and serializer in my new pipeline, so I'm kinda
guessing there's something in the path processing that hands back a
reader, but I don't know what. Any ideas?
Regards,
Emyr

It's my pattern. Very simple really - I'm going to have to look for
one that can generalise on depth. Sorry to generate noise.
