Subject Re: NPE in Fop Task
Date Wed, 15 Feb 2006 10:38:00 GMT
Actually, I wanted the FOP version, too. After searching through the
various FOP versions with the line number from the stack trace I found
that you're talking about 0.20.5.

You're using the "fop" task inside a "macrodef". I believe the NPE
happens due to the Project instance not being set on the task which the
Task.log() method needs. Maybe that's because the "fop" task is inside a
"macrodef", but I can't tell for sure. Better ask the Ant guys what's
wrong here, because I don't know. Ant is supposed to call setProject()
as far as I know.
