>
> 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}}
