Broadleaf Commerce Discussion Forums

I have set up V2.0 on Tomcat/MySQL, the Heat Clinic home page comes up correctly, but when I click on /hot-source or /merchandise link, I got the following error. I suspect some data is not set up correctly. Does anyone have a correct sample database? Or any other insights?

TemplateEngine - [THYMELEAF][12] Exception processing template "catalog/category": Base for message resolution must be a non-null and non-empty String (currently: null) (catalog/partials/productListItem:6)


Thanks

It was not data issue, but related to Thymeleaf variable scope.
