Gonzalez Adrian commented on JBIDE-4937:
----------------------------------------

A test case to reproduce the issue :

To reproduce, I'm using JBoss Tools 3.1.0.M2.

1. Create a new Seam project named seambirtweb with BIRT reporting runtime facet.
2. download the attachment JBIDE-4937-1.zip and unzip its content into the seam web project (it adds a java class, overrides components.xml, pages.xml, adds some xhtml pages and a birt report).
3. remove src/main/META-INF/persistence.xml (you can let it, but since I have a space in my workspace directory, Hibernate stops working for me ;( ).
4. start JBoss (I'm using 4.2.2) and add the webapp.
5. connect to http://localhost:8080/seam-birt-web/birttests.seam
6. select Test Birt Embed, you'll have the following error :
	ReportDesign (id = 1):
	+ There are errors evaluating script "importPackage(Packages.org.jboss.seam);
	importPackage(Packages.org.apache.log4j);
	logger.info("reportContext.getHttpServletRequest = "+reportContext.getHttpServletRequest());
	sampleReportList = Component.getInstance("sampleReportList", false);
	logger = Logger.getLogger("com.natixis.birt");
	logger.warn("sampleReportList = "+sampleReportList);
	reportsIterator = sampleReportList.getNames().iterator();
	":
	{1}.

> I'm using a Seam component in birt report (from a scripted datasource).
> Seam component is in conversation (or even session scope - same result).
> 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 (I'm accessing seam component with Component.getInstance("sampleReportList", false);).
> When I use designType="run", or frameset everything works fine. 
> Tthe issue is due to the session that isn't propagated in embed mode.
> UIDocument class creates a new URLConnection to call JBossBirtServlet without propagating session cookie JSESSIONID (or the session id parameter if session is propagated with url rewriting).
> JBossBirtServlet then calls birt engine, but in a new session context.
> So the scripted source in birt engine cannot get a reference to any object stored in the original session.
