Daniel Dekany commented on FREEMARKER-87:
-----------------------------------------
{{someString.class}} doesn't work in general in FreeMarker. Pure
{{BeansWrapper}} (which is pretty much deprecated, except in Struts maybe) does
wrap {{String}}-s into {{StringModel}} which allows that, but that's just a
weird exception, and I wouldn't utilize that. Like if you assign a string
literal to the variable in a template, {{someString.class}} won't work anymore.
Struts FreeMarker support was made long ago based on some now very old
FreeMarker version, and somehow back then they have ended up using a hack like
calling Java API methods instead of improving FreeMarker's core capabilities...
It's a bad situation.
As of {{FriendlyMapModel}}, I guess it should work. Now I understand that the
goal is that it's compatible with old Struts templates, yet {{?keys}},
{{?values}}, and {{#list ... as k, v}} are practically usable. Certainly it
would make sense to add a {{BeansWrapper}} setting for that (something like
{{boolean hideMethodsWhenListing}}).

> 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.
