koen handekyn commented on JBSEAM-2287:


let me refine that it currently does not work to my findings: it throws a 'field not found' exception as it tries to find a property called 'address.street' on the bean, and the logic for 'solving' the '.' does not seem to be triggered for params inside the '[ ]' operator. 

i'm running this inside seam so i guess i'm using already JBoss EL. i'm a bit puzzled that i trace downto a com.sun.facelets.el class but i guess that JBoss EL delages some functions to the standard implementation?

in short : i don't have a clue on where i can start to make this enhancement, if you could give a hint i want to take a loook.

kind regards

> EL extension to resolve #{bean[field]}" where field is a composite like "property.subProperty"
> today bean[field] is a means to resolve properties dynamically. 
> it does however not work for nested properties.
> it's more powerfull and more intuitive imho if one could pass an expression like "address.street" to resolve these dynamically .
> an example use case is dynamically building list pages like below where the column fields are configurable (and ideally would support projection of a street.address)
>           <c:forEach
>             items="${managedAccounts.searchFields}"
>             var="field"
>             varStatus="status"
