[rules-dev] Guvnor Build pkg error.

When trying to build a package (even using the sample pkg from drools Guvnor) I got this - "Sorry, a technical error occurred. Please contact a system administrator." This is indeed very frustrating as I need to build binary pkgs for my remote rule agents to access. I found the post here saying it is fixed. https://jira.jboss.org/jira/browse/GUVNOR-327 No details though. Can anyone shed some light on this problem if you know how to fix it? Thanks in advance for your reply. Yan
