Daniel Dekany commented on FREEMARKER-87:
-----------------------------------------
{{someString.class}} was never widely supported on the first place. For
user-defined POJO-s (not a list-like, map-like, not a date, note a string, not
number, etc., just some random class) {{obj.class}} happens to work because the
presence of {{Object.getClass()}} defines a such JavaBeans property.
There's no built-in feature to detect the Java class of arbitrary values. Maybe
you have good reason to do that, but consider if you really need that
(especially for something like a byte[]). If you do, then introduce a
{{TemplateHashModelEx}} that does that for you, and uses proper {{instanceof}}
check internally (a class name comparison is rather fragile).
> <#list map as key,value> should always iterating on map entries

> Key: FREEMARKER-87
> URL: https://issues.apache.org/jira/browse/FREEMARKER-87
> 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.
