The first question is more of a Velocity question (recommend subscribing to Velocity-User list), but in short, any $var reference in a template that is not explicity set via chucking something in the context will ouput as you see. This allows you to 'place' var tags wherever you want, and slowly fill the context as you develop and see how things look.
If you really don't want to display anything, then you use the quiet notation, which is the $!var syntax. 2nd Question: I would think so, but don't quote me on that... ;) You can also get access to the Context object in the isAuthorized(RunData) method by doing the following sneaky trick: Context context = TurbineVelocity.getContext(data); If you look under the hood of Turbine, you will see that the RunData maintains a reference inside it, and so the above call either ensures a new one is referenced and returned, or the current reference is returned. This allows you to play with the Context from a method that only has access to the RunData instance. cheers, Paul Smith > -----Original Message----- > From: Ryan Austin [mailto:[EMAIL PROTECTED]] > Sent: Friday, 13 December 2002 3:54 PM > To: Turbine Users List > Subject: Re: $data not available in Default.vm in layouts directory > > > Ok, thanks for that info.
