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 !
