Description
Using a custom search "Price Set Details for Event Participants" /civicrm/contact/search/custom?csid=9&reset=1
Gives the expected participants (rows) and fields (columns) but the data is all zeroes.
Reproduced on demo at https://drupal.demo.civicrm.org/civicrm/contact/search/custom?_qf_Custom_display=true&qfKey=e52ea1dcc0efa7b057514453937aaa93_7
This has been reported before in an earlier version http://issues.civicrm.org/jira/browse/CRM-3707 and fixed, seems it was an upgrade issue and that it may have been broken again in a subsequent upgrade.
This bug makes price sets problematic as the info for eg. number of optional dinners required can not be extracted from CiviCRM.
