In Confluence we use the Jira Issues macro to show a list of issues.
In display options, columns to display, I've got the following:
Where "parent status" is the name of my custom field of type "Parent Status Field"
When I view the page the column is empty.
If I view the search in Jira, the column is populated.
Other custom fields seem to work ok.
Note from Innovalog: this actually affects all XML exports (which is what the JIRA issues macro uses)
