Good day! I'm developing portlet using Tapestry portlet technology (4.0.2). I've created page with PropertySelection component. But it displays error "Could not find a strategy instance for class net.mycompany.portal.news.newslist.RubricSelectionModel".
How can I run my portlet successfully? Please, help me! Thanks!
