For me, that behavior sounds perfect.
However, I must confess that the reverse would also be ok.
The way I use it, when a Velocity reference/var gets rendered with the
dollar $ign and all it is just because I am doing something wrong.
=:o)
BTW, please tell me a couple of files involved in this issue. I would
like to have a starting point to better understand this bit of Velocity.
Thanks for your attention and have fun,
Paulo
