Discussion: Adding the Unified Expression Language to the framework

[Adrian Crum]

I'm considering integrating JUEL (http://juel.sourceforge.net) into the 
FlexibleStringExpander class and maybe the FlexibleMapAccessor class. 
Jacopo had expressed a desire to integrate Apache Commons EL in this 
manner 
(http://docs.ofbiz.org/display/OFBADMIN/New+Features+Roadmap+-+Living+Document), 
but the Commons EL project is based on an older EL specification.

Making this change would allow expressions like:
"Order balance: ${order.amount - payment.amount}"

anywhere the FlexibleStringExpander is used (simple methods, screen 
widgets).

What do you think?
