Hello,
I'm trying to use a decorator for an excel export, and I'm getting a very
strange,
nondescript stack trace.
The decorator is very simple; it just reformats a Date:
public class AlarmTableXlsDecorator extends TableDecorator {
public String getDts() {
String val = null;
AlarmValueObj avo = (AlarmValueObj)this.getCurrentRowObject();
if (avo.getDts()!=null) {
SimpleDateFormat format = new
SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
val = format.format(avo.getDts());
}
return val;
}
}
Debugging shows that the getDts() method is being called, and successfully
returns
a String representation of the Date object. The error occurs at some point after
this method is called.
A virtually identical decorator for a csv export of the same data works
perfectly.
What am I doing wrong? Any help would be appreciated. Thanks!
(Stack trace follows)
