[jboss-jira] [JBoss JIRA] Updated: (JBRULES-315) Support to Expression and Nested Accessors

[Edson Tirelli (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBRULES-315?page=all ]

Edson Tirelli updated JBRULES-315:
----------------------------------

        Summary: Support to Expression and Nested Accessors  (was: map lookup access for fields)
    Description: 
Would be nice to have a feature like:


Map(this.foo == bar)  as being accessed as: map.get("foo")

This can work as in the ClassFieldInspector it can tell that there is no "getFoo" method, but there is a get(xxx) method - hence it can pass in the key as the field name (as a string).

A limitation may be that we want to use a prev bound variable as a key, but I can't see how that will work short of adding new syntax (this currently stays within the current grammar which is good - and looking up fields via a String key is more then useful !).
