Daniel Dekany commented on FREEMARKER-87:
-----------------------------------------
In rare cases where calling method on a {{Map}} is needed (as opposed to using
{{?values}}, {{?keys}} and {{#list map as k, v}}), you can use
{{map?api.someJavaMethod()}}. (But calling Java methods directly means that
your template will depend on if a variable is a real {{Map}} or just something
wrapped as {{TemplateHashModel}}.) Also note that the template language has no
separate namespace for methods and plain variables, that is, if {{foo.m()}}
works, then {{foo.m}} and {{foo["m"]}} returns the method itself as value.
Hence it's logical that then {{m}} is among the keys as well, and hence it
better if it's not a hash item at all.
> <#list map as key,value> should always iterating on map entries

> 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.
