Parameters gone after velocity merge

[Leandro Rodrigo Saad Cruz <le...@ibnetwork.com.br>]

Hi all. I'm crossposting this message because I think this is related to
velocity too !

I'm trying to write a custom Screen that handles some security and
layout management but , at some stage, I get an empty parameter parser. 

Here is the cause of my error : the method clear() is invoked by
velocity when it merges the screen template (stack trace bellow) Do you
why is that ?
