Thank you for the example. But I still can't work with trinidad. My command buttons just don't post the form! <tr:commandButton text="Register" action="#{someAction}"/> is rendered to something like this: <button type="button" onclick="submitForm(somethinghere)>Register</button> If I provide attribute type="submit" for the commandButton the warning is shown: anonymous wrote : type="submit" Property 'type' is not on type: org.apache.myfaces.trinidad.component.core.nav.CoreCommandButton | How it is possible that you are using this attribute in your example?
