Issue Summary

The Issues Calendar dashboard gadget (com.atlassian.jira.ext.calendar) returns an empty calendar (no issues rendered on any day cell) when dateFieldName=resolutiondate is selected. All other date fields (Created, Updated, Due Date) render correctly on the same filter/dataset.

Steps to Reproduce

• Create issues and resolve them (ensure resolution date is populated)

• Create a saved filter that returns these resolved issues (e.g., project = TEST AND resolution != Unresolved)

• Add the "Issues Calendar" gadget to a dashboard

• Configure with the saved filter and set Date to Display = Created → issues render correctly

• Change Date to Display to Resolved → calendar grid renders, but all day cells are empty

Expected Results

Issues should render on their respective resolution date in the calendar, same as they render for Created/Updated/Due Date.

Actual Results

Calendar HTML is generated (HTTP 200), but every day cell contains no issue data. Only the yellow-colored box is visible.

Workaround

Currently, there is no known workaround for this behaviour. A workaround will be added here when available.
