Symptoms

Using the create wizard to start a new decision it's unable to find any users while searching in either the Owner or Stakeholders field.

Cause

Confluence's index wasn't properly updated or could be culprit.

Resolution

1. Shut down your Confluence server.
2.  Make a backup of your <confluence-home>/index/plugin directory if it exists. This is where the Usage Tracking plugin stores it's index for the usage statistics and it cannot be rebuilt.
3.  If you're in Confluence 4.2 onwards, make a backup of your <confluence-home>/index/edge directory if it exists. This is where the index of Likes and Popular Content are stored and cannot be rebuilt.
4. Remove the <confluence-home>/index directory.
5. If in step 2, you have the <confluence-home>/index/plugin directory, create the <confluence-home>/index directory and copy in the backup of <confluence-home>/index/plugin directory made in step 2.
6. If in step 3, you have the <confluence-home>/index/edge directory, create the <confluence-home>/index directory and copy in the backup of <confluence-home>/index/edge directory made in step 3.
7. Restart server.
   A new index directory will be created upon restart of your application if it does not exist.
8. Now perform the manual re-indexing of your site to build a brand new index from scratch.
