I have two custom date fields say x and y and i want to list issues in jira issue filter bar using x>y. Now default jira doesn't allow me to directly compare any date fileds whether default jira date fields or custom ones. But script runner plugin atleast allows me to compare directly 2 default jira date fields like resolutiondate>duedate,etc.But script runner doesn't allow to compare 2 custom date fields say x>y. I tried out issuefunction in datecompare("","x>y") but just error
