trinidad: disable debug output

[arne anka]

hi,
i play around with tr:table and when hitting the "next XX" link, a lot of  
output, apparently xml response from ppr, is written to stdout/stderr.
this makes it very hard to read the messages i am interested in -- so,  
does anybody know how to disable this?

<context-param>
        <param-name>facelets.DEVELOPMENT</param-name>
        <param-value>false</param-value>
</context-param>

in web.xml seems to have no effect.

thanks in advance
