[rules-users] Guvnor and oryx designer problems

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/1.0.0.026-SNAPSHOT/
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/trunk/target/
(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.
