Christoph Reck commented on VELOCITY-496:
-----------------------------------------
Claudes request affects the ueberspector, but has a minor BC issue.
The ${map.{foo.bar}.baz}schmoo syntax is a parser change - and could make it
into 1.5 if it is a minor change. Who can check if the parser can be updated
for this syntatic upgrade? Please note that the unit tests must pass after a
parser change.
Patches are welcome as Will states!

> Key: VELOCITY-496
> URL: http://issues.apache.org/jira/browse/VELOCITY-496
> Project: Velocity
> Issue Type: Improvement
> Components: Engine
> Affects Versions: 1.6
> Reporter: Claude Brisson
> Priority: Minor
>
> This is a quite prospective proposal that emerged from a discussion in a
> VelocityTools JIRA issue (https://issues.apache.org/jira/browse/VELTOOLS-69).
> Its goal is to have the short syntax $map.foo.bar chek the existence of
> $map.get("foo.bar") when $map.foo is null.
> Backward compatibility is 99%, since it only breaks templates that rely on
> $map.foo.bar being an invalid reference while having foo.bar as key in map.
> The implementation doesn't look obvious, and we must ensure that there are no
> other side effects, yet this behaviour can be quite usefull when dealing with
> HTML field names that contain a period.
