> -------------------------------------------------------------------

> Key: FREEMARKER-148
> URL: https://issues.apache.org/jira/browse/FREEMARKER-148
> Project: Apache Freemarker
> Issue Type: Task
> Reporter: Siegfried Goeschl
> Assignee: Siegfried Goeschl
> Priority: Major
>
> "DataSources" is exposed to get/find documents - as suggested it would be nice to make the access more aligned with FreeMarker usage.
> The way to go is to wrap "DataSources" and expose "TemplateSequenceModel" and "TemplateHashModel".
> So accessing the first datasource would look like
> {code:java}
> ${GsonTool.toJson(YamlTool.parse(DataSources[0]))}
> {code}
> instead of
> {code:java}
> ${GsonTool.toJson(YamlTool.parse(DataSources.get(0)))}
> {code}
