> Doesn't support org.bson.Document's correct order of keys.
> ----------------------------------------------------------

> Key: FREEMARKER-67
> URL: https://issues.apache.org/jira/browse/FREEMARKER-67
> Project: Apache Freemarker
> Issue Type: Bug
> Components: engine
> Affects Versions: 2.3.23, 2.3.24-incubating, 2.3.25-incubating,
> 2.3.26-incubating
> Environment: Windows7, jdk1.8.0_131, Tomcat 8.0.45, SpringMVC
> 4.3.10.RELEASE, mongo-java-driver 3.4.2
> Reporter: Pu Zhongqiang
> Priority: Minor
> Labels: features

> In mongodb's Java Driver 3.x, org.bson.Document is a representation of a bson
> document as a Map. Although org.bson.Document is not a subclass of
> LinkedHashMap, it really DOES maintain a meaningful order for its keys.
> It works good if I use LinkedHashMap to load data.
> {code:java}
> LinkedHashMap<String,Object> accepted_sorts = new LinkedHashMap<>();
> accepted_sorts.put("-favorite_time", "Hello");
> accepted_sorts.put("-publish_time", "Welcome");
> model.put("accepted_sorts", accepted_sorts);
> {code}
> {code:html}
> <#list accepted_sorts?keys as value>
> ${value?string}
> </#list>
> <br>
> <#list accepted_sorts as key,value>
> ${key?string},${value?string}
> </#list>
> {code}
> it rendered as:
> {code:html}
> -favorite_time -publish_time
> -favorite_time,Hello -publish_time,Welcome
> {code}
> But Freemarker doesn't support org.bson.Document's correct key order. You
> can see my test below:
> {code:java}
> Document accepted_sorts = new Document();
> accepted_sorts.put("-favorite_time", "Hello");
> accepted_sorts.put("-publish_time", "Welcome");
> model.put("accepted_sorts", accepted_sorts);
> {code}
> {code:html}
> <#list accepted_sorts?keys as value>
> ${value?string}
> </#list>
> <br>
> <#list accepted_sorts as key,value>
> ${key?string},${value?string}
> </#list>
> {code}
> it rendered as wrong order:
> {code:html}
> -publish_time -favorite_time
> -publish_time,Welcome -favorite_time,Hello
> {code}
> So, in the end, I wish freemarker can add support for org.bson.Document's
> correct order of keys.
