                 URL: https://jira.jboss.org/jira/browse/JBIDE-3878

    Affects Versions: 3.0.0.GA
            Reporter: Alexey Kazakov
            Assignee: Alexey Kazakov
             Fix For: 3.0.0.GA


EXECUTE: Create Seam Web Project
EXECUTE: Create new class:

import org.jboss.seam.ScopeType;
import org.jboss.seam.annotations.Install;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Observer;
import org.jboss.seam.annotations.Scope;
import org.jboss.seam.annotations.Startup;
import org.jboss.seam.security.Identity;

@Scope(ScopeType.SESSION)
@Install(precedence=Install.APPLICATION)
@Startup
public class MyIdentity extends Identity {
	@Observer("myEvent")
	public void foo() {}
}

EXECUTE: Ctrl+S
ASSERT: There is an error message on foo method: "Only component class can have @Observer method"

But now there is not such error marker but NPE is thrown:
