Re: How to connect to secondary ports out of p:choose?

Thanks, Norm, that helps a lot! It works as expected, and I think I now understand the pipe model a bit better—pipes all the way down, inside as well as outside of the branches of the p:choose container.

Thank you!

Doug

In brief, bindings for ports that aren’t “primary” isn’t automatic. Something like this will do the trick:

<p:when test="$doctype='doc_a'">
    <p:output port="result" primary="true"/>
    <p:output port="secondary" sequence="true" pipe="secondary@proca"/>
    <p:xslt name="proca">
        <p:with-input port="stylesheet" href="process_a.xsl"/>
    </p:xslt>

That establishes a binding between the secondary output port of the XSLT step (named proca) and the secondary output port of the p:when.

Hope that helps.

                                        Be seeing you,
                                          norm
