             Summary: Configuration Admin tab not working when Metatype Service API is missing
                 Key: FELIX-3784
                 URL: https://issues.apache.org/jira/browse/FELIX-3784
             Project: Felix
          Issue Type: Bug
          Components: Web Console
    Affects Versions: webconsole-4.0.0
            Reporter: Felix Meschberger
            Assignee: Felix Meschberger
             Fix For: webconsole-4.0.2


When the MetaType Service API is missing the Web Console Configuration Admin tab is non-operational:

* displaying the "configMgr" label instead of a title
* sending 404/NOT FOUND when accessed
* logging an error message (see at the bottom)

The ConfigurationAdmin plugin should be refactored such, that:

  * It operates without the MetaType Service API available
      (already copes with missing MetaType Service instance)
  * It properly handles missing Configuration Admin API
      (same as for missing Configuration Admin Service instance)
