[rules-users] Troubles with Oryx designer in Guvnor - jBPM 5.1.CR1

[Dan Seaver]

I'm attempting to use the Oryx designer in Guvnor, however I can't seem to
save / redisplay any diagram. I've tried it with various configurations,
including using the jBPM demo, but always get the same results. After I save
the newly created BPMN diagram, the Oryx designer refreshes to a blank
diagram. The new diagram name is on the list of Guvnor processes (for the
default package), and when I try to open it, I get the same blank diagram.

After starting the jBPM demo (5.1.CR1), I see the h2 database started, jboss
started and the human task service started. The jboss log looks pretty clean
except for an SLF4J error and a mention that the persistence provider caller
for org.jbpm.persistence.jpa does not implement the ejb3 spec correctly.
Also, there is an error regarding the log4j FileAppender.

Then I goto Guvnor with FireFox (or Chrome or IE6) and create the new BPMN
process. I get the following message in the jboss log:

2011-06-20 16:00:05,288 INFO  [STDOUT] (http-localhost%2F127.0.0.1-8080-3)
(null: -1, -1): Premature end of file.

Then I create the process with the designer:

Anybody have any ideas on what could cause this on my system and how I may
be able to solve it? Any help would be appreciated.
