3. Create Web Content using this Structure
4. Add a translation for the Web Content and publish
5. Add a new Asset Publisher ADT (use the attached one, select Velocity as Language)
6. Add an Asset Publisher Portlet to a page and use the previous ADT

>> Result:

You'll receive the following exception:

ERROR [RuntimePageImpl-2][LocaleTransformerListener:205] null
java.lang.NumberFormatException: null
at java.lang.Long.parseLong(Long.java:404)
at java.lang.Long.parseLong(Long.java:483)
[...]

>> More details:

The problem appears on LocaleTransformerListener, when trying to do:

Long.parseLong(tokens.get("article_group_id"));

The problem is that inside the tokens has map does not exist an article_group_id key. This map was created in JournalArticleImpl.getContentByLocale(String languageId) method.
