I can use from velocity what is really in the velocity context. So, if
UrlHelper is not in the context, i cant use it.
BUT with the extension of velocity-tools, and particulary the toolbox
manager included in the VelocityView package, you can make any tools
available to the templates. This mechanism is the base for the use of the
struts framework with velocity, where some struts ressources are made
available via the toolbox manager.
Hum, of course the choice of a WebWorkVelocityServlet is understandable for
managing the ww tags, but relying on Velocity Tools is maybe a more stable
choice, or complementary ...

That was my question, my converter extends DefaultTypeConverter, but if my
converter is unable to convert, how can i add field error message to WW2 ?
I've got no context attached to WW2.

I agree, it would be just for convenience
