[rules-users] process-designer deserialization error (new ISSUE)

[Antoine Toulme]

Process Designer went a long way since, I recommend you try this:
http://www.intalio.org/public/maven2/com/intalio/bpms/web/designer/1.0.0.040/designer-1.0.0.040.war

You will need to tweak the web.xml to support Tomcat I think.

Good luck!

Antoine
