[jira] Commented: (VELOCITY-496) Allow periods in references secondary keys.

["Christoph Reck (JIRA)" <ji...@apache.org>]

    [ http://issues.apache.org/jira/browse/VELOCITY-496?page=comments#action_12450329 ] 
            
Christoph Reck commented on VELOCITY-496:
-----------------------------------------

For completeness: the implementation should also consider that a property access after the map access might be used:
  $map.foo.bar.baz
meaning
  $map.get("foo.bar") .getBaz()

So a descision is needed if this feature will be supported.

Also consider having eplicit syntaxt for a map access with a dotted key: 
  $map.{foo.bar}.baz and ${map.{foo.bar}.baz}schmoo
which would resolve this issue and my completeness request

> 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.
