unable to resolve Type Declaration class
----------------------------------------

                 Key: JBRULES-2348
                 URL: https://jira.jboss.org/jira/browse/JBRULES-2348
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-compiler, drools-guvnor
    Affects Versions: 5.1.0.M1, 5.0.1.FINAL
         Environment: Ubuntu 8.04
            Reporter: Richard Ambridge

Using the following code to create a Knowledge Base from a guvnor compiled pkg, (download the pkg and put in /tmp/my.pkg)

 
KnowledgeBaseConfiguration conf = KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
            conf.setOption(EventProcessingOption.STREAM);
            KnowledgeBuilder builder = KnowledgeBuilderFactory.newKnowledgeBuilder();
            try {
                File f = new File("/tmp/my.pkg");
                InputStream stream = new FileInputStream(f);
                if (stream == null) {
                    jlog.fatal("Unable to find rule pkg");
                } else {
                    jlog.info("adding pkg");
                    builder.add(ResourceFactory.newInputStreamResource(stream), ResourceType.PKG);
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
            KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(conf);
            kbase.addKnowledgePackages(builder.getKnowledgePackages());
            jlog.info("setup creating knowledge session");
            ksession = kbase.newStatefulKnowledgeSession();
            jlog.info(" setup ksession created");


The pkg was created from Guvnor.

If in the package declaration area in Guvnor,  (where you put the import statements)
If I put
declare Signature
 @role ( event )
end

then build the package, save it to disk /tmp/my.pkg
on startup I get:

[#|2009-11-24T14:50:38.944+0000|WARNING|sun-appserver2.1|javax.enterprise.system.stream.err|_ThreadID=12;_ThreadName=pool-1-thread-3;_RequestID=7c35064d-757e-4519-b5eb-433db89e168d;|org.drools.RuntimeDroolsException: unable to resolve Type Declaration class 'Signature'
        at org.drools.compiler.PackageBuilder.addPackage(PackageBuilder.java:754)
        at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:515)
        at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:25)


I am unable to declare an object as an event type in guvnor. This prevents any rules creation and compiling :(

Attached is the workbench from eclipse, and the guvnor repository export
