We implementing own portlet - this portlet shoudl display web-content by specified articleId.
So, to do it we are using followed code:

<%
JournalArticleDisplay articleDisplay = JournalContentUtil.getDisplay(themeDisplay.getScopeGroupId(), String.valueOf(articleId), null, themeDisplay.getLanguageId(), themeDisplay);
%>

<%= displayArticle == null ? StringPool.BLANK : displayArticle.getContent() %>

this works fine for normal articles - but in case we are trying to display template driven article - we always got null from getDisplay method.
