Calling overridden superclass methods in VTL

[Christopher Schultz-2]

All,

I was reading
http://wiki.apache.org/jakarta-velocity/BuildingSecureWebApplications
and I noticed that, about halfway down the page, there is this warning
about creating subclass wrappers around objects:

"
Subclassing is not helpful as the template designer can call a method
from a superclass with the VTL $reference.super().badmethod().
"

I no documentation of the "super" method neither in the Developer Guide
nor in the VTL Reference. As far as I know, calling "around" a virtual
method is not possible even using regular Java.

Is this statement apocryphal, or was/is this possible at some point?

Thanks,
-chris

No, there was never such a feature.  I think the statement should be
something like:

$reference.badMethodDefinedInSuperClass()

The point seems to be that Velocity supports calling any public method
of an object defined in a public class/interface, not merely those
defined in the subclass.  Which is quite true.
