[jboss-as7-dev] Problems with the OSGI subsystem (ConfigAdmin)

Hi All. I created an OSGI application that uses the ConfigAdmin subsystem and had no problems with felix. Now I need to make my application available with jboss. I successfully deployed my application and the bundle successfully starts. However, the 'updated' method of my ManagedService get's never called. I can't see any error inside the log file. Do you have any idea where to look to discover some more information? Thanks in advance, Massimiliano
