I am using Cocoon 2.0.4 from the command-line to generate single documents (no links
are followed):
java -Xmx256m -Xss2048k \
-cp $CLASSPATH \
org.apache.cocoon.Main \
-c $HOME/cocoon.war \
-C $HOME/cocoon.war/WEB-INF/cocoon.xconf \
-k $HOME/cocoon.war/WEB-INF/logkit.xconf \
-u INFO \
-r no \
$URL
This works fine, but when I request one URL, the pipeline for this URL is executed
three times! I can see this by including an action component which writes to a log
file.
When I request a profile as well, in the profiling output there are two <pipeline>
elements for the original URL, one with count="2" and one with count="1" (which again
suggests that the pipeline is executed three times). The pipeline with count="1" has
an extra <element> with role="<translator>" added right before the serializer.

My question is: Why is the pipeline executed three times (and not twice or just once)?
Is it possible to bypass this behaviour and execute it only once, from the
command-line?
We are using cocoon for some CPU-heavy offline transformations, and executing the
pipeline once or three times makes a lot of difference.
Thanks for considering this question, and for any answers!
