Description of problem: When a user tries to (erroneously) 'enable' a deleted plugin, the message returned is at least somewhat inaccurate/incorrect. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. Administration > Plugins 2. Delete (but do not purge) hadoop plugin 3. Show Deleted 4. On resulting UI, note the two (!) icons for hadoop -- Enabled and Deployed, respectively -- in other words, no, it is neither enabled nor deployed. 5. Attempt to enable hadoop plugin Actual results: * green box reading "No disabled plugins were selected. Nothing to enable " Expected results: * Minimally, the error message shouldn't say anything about "No disabled plugins", when the UI indicates that it is disabled (albeit not deployed either) * error message should probably red * Probably should disable this checkbox for deleted plugins Additional info:
