[xwiki-users] com.xpn.xwiki.doc.XWikiDocument.getStringValue("date_property_name") returns empty String

Hi, I am trying to get the String value of a Date Property. I am using the following code: *def obj = doc.getObject("SSI-Internal.CreateIssue");* *def summary = obj.getStringValue("environment");* *def date = obj.getStringValue("due_date");* *doc* is of type *com.xpn.xwiki.doc.XWikiDocument* and *environment* is a TextArea property. I can get the String value of the TextArea property, but I can't get the String value of the Date property (*due_date*). How can I get the String value of a date property? Thanks, Abel
