Christian Riedel commented on TAP5-843:
---------------------------------------
Does that issue also cover expansions? A nested expansion like that would save
lots of code: ${asset:context:images/${someObject.imageName}}
> Allow nested symbol definitions

> Key: TAP5-843
> URL: https://issues.apache.org/jira/browse/TAP5-843
> Project: Tapestry 5
> Issue Type: New Feature
> Components: tapestry-ioc
> Affects Versions: 5.2.0.0
> Reporter: Howard M. Lewis Ship
>
> It would be nice if a Symbol's definition could be nested, i.e.
> ${foo.${bar}}
> This would evaluate ${bar} forming a new symbol name prefixed by 'foo', which
> would then itself be evaluated.
> Boy this is going to complicate the circular logic detection code!
