Hi Kevin,

I wonder if you could use mixin parameters for this?
Since the value to be operated on is likely to have different names  
for different components (certainly no guaranteed name), it seems like  
specifying a mixin parameter which tapestry will "autobind" is perhaps  
the way to go?
Then you could make your adjustments in (probably) begin render?
