[jboss-user] [JBoss Tools Users] - birt - Seam component always null with birt embed

[gonzalad]

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 !
