You can just use {{DefaultObjectWrapper}} or {{DefaultMapAdapter}} if you only
want to avoid methods appearing as keys. Implementing {{TemplateHashModelEx2}}
is certainly not the right fix alone, as you will still get the unwanted keys
with {{?keys}}. But again, I'm not sure what the purpose of
{{FriendlyMapModel}} is, and why do chose {{MapModel}} as its super class. I
would void {{MapModel}}.

> Project: Apache Freemarker
> Issue Type: Bug
> Components: engine
> Affects Versions: 2.3.27-incubating
> Reporter: Yanming Zhou
> Priority: Major
> Attachments: MapIteratingTest.java
>
>
> I'm using struts2, use FriendlyMapModel instead of default MapModel, It works
> fine except map have key such as "size", the value will be unexpected
> SimpleMethodModel, I think freemarker should always use entry value for
> directive <#list map as key,value>, not matter how MapModel works, MapModel
> should only affect map.size and map.get('size').
> I attached a test case.
