             Summary: The ability to declare indexed property getter/setter in 
customised JexlArithmetic implementation
                 Key: JEXL-222
                 URL: https://issues.apache.org/jira/browse/JEXL-222
             Project: Commons JEXL
          Issue Type: Improvement
    Affects Versions: 3.0
            Reporter: Dmitri Blinov
            Priority: Minor


At the moment we have the ability to declare a specific getter/setter method in 
customized JexlArithmetic class that will be used by Jexl engine when engine 
tries to get access to a property of some object. This is great extension point 
of the Jexl but I have come to a situation where I need the same technics to be 
applied to indexed properties. For example I'm scripting org.w3c.dom.Element 
object by setting its attributes via its 
{code}Element.setAttribute(java.lang.String name, java.lang.String value) 
{code} method. In Jexl I use standard indexed property access syntax like the 
following: {code} node.attribute.id = "12345"; {code} The problem lies with the 
last argument of the setAttribute method which is of String class. And for Jexl 
standard indexed property setter to work I should always remember that in 
script I need to cast specified property value to a string, which is 
error-prone and lacks, in my understanding, scripting easiness. I see the 
solution as to introduce custom indexed property setter in more generalized 
form, accepting Object type as a value so it could cast a value to String 
before calling {{Element.setAttribute}}
