I have a calculated date time field and it is set to 10 days from issue created date. The formula used is
<!-- @@Formula: org.apache.commons.lang.time.DateUtils.addDays(issue.get("created"),10) -->
While this works and displays the date on View Issue screen, in Issue Navigator screen it is not displaying the date and I see an exception in the log.

I have only one project and just created one issue to test it and it fails. So it is not something to do with null value in formula.
