Hello everyone, I have added a sample.bpmn workflow (this is the default eclipse sample with an extra Script Task printing goodbye to the console before ending) from eclipse to guvnor, then i tried to edit the sample.bpmn from guvnor using the oryx designer 1.0.0.026-SNAPSHOT from http://anonsvn.jboss.org/repos/labs/labs/jbossrules/contrib/designer/1.0.... but no diagram is presented. The editor is shown (after removing the servlet-api*.jar, slf4j*.jar and log4j*.jar (three or four jars in total) related jars from the designer and placing two of the latest slf4j*1.6.0.jar as found in guvnor.war into the libs of the jboss AS), but the diagram is never displayed. I've tried the following combinations, - jboss-4.2.3.GA and jboss-5.1.0.GA - guvnor version 5.1.1 and 5.2.0 SNAPSHOT from https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/t... (when tried the 5.2.0 snapshot the editor is not presented at all, I only get an "Error" dialog stating "Sorry, a technical error occured. Please contact a system administrator". The corresponding error in the server.log of the AS is provided at the end of the post. If i ran the editor in its own tab via localhost:8080/designer/editor?uuid=the id of the asset, the editor is shown but empty again) - oryx designer 1.0.0.026-SNAPSHOT So the question is what is the latest oryx designer version working correctly with guvnor version 5.1.1 or 5.2.0 snapshot. Is anyone else having such problems or am I doing something wrong here?? Thanks guys for your time and help.... looking forward to hearing from you. ---- log ----suspicious part?? 2010-11-08 16:52:38,725 INFO [STDOUT] (null: 5, 196): schema_reference.4: Failed to read schema document 'http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/main/resources/change-set-1.0.0.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>. 2010-11-08 16:52:38,726 INFO [STDOUT] [2010:11:312 16:11:726:info] KnowledgeAgent applying ChangeSet 2010-11-08 16:52:38,726 INFO [STDOUT] [2010:11:312 16:11:726:debug] KnowledgeAgent notifier subscribing to resource=[UrlResource path='http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/defaultPackage/LATEST'] 2010-11-08 16:52:38,771 INFO [STDOUT] [2010:11:312 16:11:771:debug] ResourceChangeNotification subscribing listener=org.drools.agent.impl.KnowledgeAgentImpl@11dd4fb to resource=[UrlResource path='http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/defaultPackage/LATEST'] 2010-11-08 16:52:38,771 INFO [STDOUT] [2010:11:312 16:11:771:debug] ResourceChangeScanner subcribing notifier=org.drools.io.impl.ResourceChangeNotifierImpl@179c1cb to resource=[UrlResource path='http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/defaultPackage/LATEST'] 2010-11-08 16:52:38,871 INFO [STDOUT] [2010:11:312 16:11:871:debug] KnowledgeAgent rebuilding KnowledgeBase using ChangeSet ------.... and some more........ -----exception part 2010-11-08 16:52:40,543 INFO [STDOUT] Loading session data ... 2010-11-08 16:52:40,598 INFO [STDOUT] Error loading session data: java.lang.reflect.InvocationTargetException 2010-11-08 16:52:40,598 INFO [STDOUT] Creating new session data ... 2010-11-08 16:52:40,662 INFO [STDOUT] Successfully loaded default package from Guvnor 2010-11-08 16:52:50,783 INFO [STDOUT] DEBUG 08-11 16:52:50,782 (LoggingHelper.java:debug:65) Package: defaultPackage, asset: sample.
