Re: [chain] add expression evaluation?

[Matt Sgarlata]

Sorry if I'm getting annoying with my plugs for the Morph framework, but 
Morph's SimpleLanguage would allow users to use whatever expression language 
they are already familiar with (the Struts/BeanUtils language, the Spring 
language, or JSTL).  The SimpleLanguage works with Maps out-of-the-box, and 
thus implicitly with Chain's context notion.

I will be focusing on writing test cases for Morph this weekend, so 
SimpleLanguage should be useable by Monday.

I'm +1 for it.

I hadn't seen that -- and it's very cool!
But a quick look leads me to believe that it would be evaluated only once, 
at XML ingestion time, while in the context I'm thinking of, the value of 
the expression would be dependent on the runtime state of the context. 
With Chain, I think that would be very powerful.
