[rules-users] RuleAgent in webservice

[Esteban Aliverti]

Hi, I've fixed this bug in the trunk few days ago:
https://jira.jboss.org/browse/BRMS-320
<https://jira.jboss.org/browse/BRMS-320>The bug is still open because I
don't have enough permissions in jira yet. ;)
Please try it out and let me know the results.

Best,
