In OnDemand, using a date picker in a customer portal request form doesn't work, leaving an error message in the browser console:
"Uncaught RangeError: Maximum call stack size exceeded" in Chrome or "too much recursion" in Firefox.
This is due to a change in the underlying JIRA code in OnDemand, and does not affect Service Desk installations from Atlassian Marketplace. Service Desk 1.2.4 contains a fix to stop the console error and will be released to OnDemand shortly, but the date picker does nothing.
We will update this issue when we have details about the fix in JIRA being deployed to OnDemand.
