問題

When viewing an issue, the Work Log tab is either empty or doesn't display all work logs

However, the History tab shows that work is indeed logged

原因

When entering the work log, the user restricted this entry to certain Roles/Groups

The logs will appear if a user part of this role views the issue

User part of the restricted role	User not part of the role

ソリューション

If you want all work logs to be displayed, then you will have to manually change the work logs such that they are not restricted

1. Log in as a user who can view the work log
2. View the issue's work log tab
3. For the affected entry, hover over it and click on the pencil icon on the top right of it
   
4. Edit the entry so that All Users can view it

You can run the following queries against your JIRA database to find the affected issues (these queries are written for PostgreSQL. Modification might have to be made to suit the database your JIRA is using)

1. To find all work logs which are restricted to certain Roles

   SELECT a.pkey, b.issuenum, c.author, d.name AS "Role" FROM project a JOIN jiraissue b ON a.id=b.project JOIN worklog c ON b.id=c.issueid JOIN projectrole d ON c.rolelevel=d.id WHERE c.rolelevel IS NOT null ORDER BY pkey, issuenum;
   
   

2. To find all work logs which are restricted to certain Groups

   SELECT a.pkey, b.issuenum, c.author, c.grouplevel FROM project a JOIN jiraissue b ON a.id=b.project JOIN worklog c ON b.id=c.issueid WHERE c.grouplevel IS NOT null ORDER BY pkey, issuenum;
