    birt - Seam component always null with birt embed

      Hello,

      I'm using a Seam component in birt report (from a scripted datasource).
      When I try to access a Seam Component from a birt report and when I use embed mode(designType="embed"), Seam component is always null.
      When I use designType="run", everything works fine.

      I don't understand why.
      It appears to me to have a relation with UIDocument's logic when we call JBossBirtServlet with an URLConnection :

      URL birtURL = new URL(urlString);
URLConnection connection = birtURL.openConnection();
InputStream stream = connection.getInputStream();

      When I change this code from UIDocument code to use requestDispatcher.include, it works fine.

      Should I open a JIRA issue (with test case) ?

      Thanks for your help !

      And the open method from my scripted datasource :

sampleReportList = Component.getInstance("sampleReportList", false);
logger = Logger.getLogger("com.natixis.birt");
logger.warn("sampleReportList = "+sampleReportList);
reportsIterator = sampleReportList.getNames().iterator();
