Re: (no subject)

Unfortunately you can't do that out-of-the-box. Some may say that you
should use user?keys, but that will return not only the property names
but the method names too. But you could write a TemplatMethodModelEx
(that's like a #function only it's implemented in Java) that tries to get
the non-wrapped Java object with
((AdapterTemplateModel) arg).getAdaptedObject(Object.class)
then gets the property names with the java.beans API-s, builds a
freemarker.template.SimpleSequence based on what it sees, and returns
it. So you create a such TemplatMethodModelEx, let's call it
com.example.GetPropertyNamesMethod, and then put it into an #import-ed
ftl where you have
<#assign getPropertyNames = "com.example.GetPropertyNamesMethod"?new()>.
