[rules-users] [Designer] Problem installing service from repository

Hi, I'm using Designer 2.2 with Guvnor 3.4 in a Jboss AS 7.1. I could connect to this service repository url: http://people.redhat.com/kverlaen/repository in the Designer editor. I've selected the Twitter service but I got this error: 19:58:58,896 ERROR [org.jbpm.designer.web.server.JbpmServiceRepositoryServlet] (http--127.0.0.1-8080-5) Could not find the package for uuid: c3142f2a-084b-423f-8afa-640c84140075 Am I missing something ? regards, Cristiano
