Re: Expression Handling Again

AFAIK there are only two ways to get something out of a WM template 
expansion -- capture the result of the expansion, or pull something from 
the context.  Actually I suppose you could use the #bean directive to 
create a "global" variable and then get it from the Broker.

Maybe if you can explain your requirements we could think of a way of 
doing what you want.
