Exposing all the globals in FreeMarker

<#list .globals?keys as vals>
${vals}
</#list>


FreeMarker template error: For "?keys" left-hand operand: Expected an extended
hash, but this has evaluated to a hash (wrapper: f.c.Environment$4):
==> .globals  [in template "contents/globals.ftl" at line 9, column 8]

In other words, how to render the keys of a hash which is not extended in FreeMarker? (I'm using node.js with fmpp, rather than developing in Java)

As already stated in the comments, the keys of globals are not accessible. globals are a hash and no extended hash. This means, you can not access their keys and values using the built-ins for hashes.

You can tell if a hash is extended (and thus supports those built-ins) by using is_hash_ext.
