Spring Portlet MVC with Freemarker

[younes]

Dears,
I'm trying a basic "Hello Freemarker Portlet" with no luck. The deployment of the portlet in Liferay 6.0 goes fine. But when I'm trying to add the portlet to a page, I got the following exception:

java.lang.NullPointerException

Hi younes.
Have you any solution on your trouble?

[younes]

Hi buslovskas,

Not at all. I have got a reply through JIRA saying that the issue is due to Freemarker not Spring Portlet MVC and hence can be resolved only by Freemarker team. I have stopped at that level.

However, a comment has been add by Barrie Selack to the JIRA (see https://jira.springsource.org/browse/SPR-7830). I hope it will help.

Warm regards.

Younes
