Subject [jira] Commented: (FELIX-2844) Disabled SCR Component can't be re-enabled anymore
Date Fri, 18 Feb 2011 19:15:38 GMT

    [ https://issues.apache.org/jira/browse/FELIX-2844?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12996570#comment-12996570
] 

Felix Meschberger commented on FELIX-2844:
------------------------------------------

Point is that a component only has a component ID if it is activated. Consequently when the
component is disabled the id is removed again and is displayed as -1 in the listing.

To fix this "problem" the command also support the component name to specified. So to enable
you can do

  g! scr:enable MyComponent

I have updated the documentation at [1]  (to be refreshed in a few hours).

As a consequence this is not really a bug and I resolve it appropriately.
