On node configuration, the configuration event published to subscribers contained an item element with an id='configuration' instead of a configuration element. Probably a version related issue.
May be a versioning issue (1.8 vs. 1.12)
Updated to provide configuration element.
This was changed between version 1.7 and 1.8. So this can be committed since the server is already supposed to support 1.8.
ID is now set to node id
