[orbeon-user] xslfo-serializer

[jel]

I would like to generate a pdf file with the xslfo-serializer processor generated within a page-flow that is called from an embedding portlet.

I am calling the pipeline the following way:
        <action when="/form/action = ''" action="/organizer/pages/case/edit/pageparts/chart/illustrationActionModel.xpl"/>
(there is no result page)

(and there is no output of the pipeline, the xslfo-serializer processor is the last processor in the pipeline)

When the processor (xslfo-serializer) had run, either  the pdf file, or the "save-open dialog box" did not appear in my browser, in spite of the fact that, the processor appears to run successfully, and then I got the following exexception:

org.orbeon.oxf.common.ValidationException: null, line 1, column 1 : Content is not allowed in prolog. : null, line 1, column 1: Content is not allowed in prolog.

What do you think I could do?
