Just today we noticed that clicking the applinks menu option for any repository results in the following error message:

No entity exists with key appdev of type com.atlassian.applinks.api.application.fecru.FishEyeRepositoryEntityType
Status code: 400

All of our repositories are restricted by LDAP filters.
The error only appears for those repositories where I'm not a member of the LDAP group with repository access.
Given that only Fisheye admins would be able to add applinks, it seems like Fisheye is looking in the wrong place for permissions (repo-view permissions instead of admin permissions)
