Re: [Springframework-developer] java.util.Map fields and commons validator

[Colin S. <col...@ex...>]

The existing spring approach is also similar to OGNL. In OGNL, '(' is 
used for an actual method call, since you can also call methods, not 
just navigate graphs.

I'm a bit of mixed feelings about adding '(' support in the BeanWrapper. 
It would make the validation usage a bit more similar to 
commons-validator/struts, but would muddy the water for general 
expression syntax.

Karl, your issue with the setup right now is that people can't take 
their existing definitions exactly as-is?
