For now the dummyForm feature is deprecated.
You can reenable it by adding the following to your faces-config.xml
<renderer>
<component-family>javax.faces.Command</component-family>
<renderer-type>javax.faces.Button</renderer-type>
<renderer-class>org.apache.myfaces.renderkit.html.jsf.ExtendedHtmlButtonRenderer</renderer-class>
</renderer>
<renderer>
<component-family>javax.faces.Command</component-family>
<renderer-type>javax.faces.Link</renderer-type>
<renderer-class>org.apache.myfaces.renderkit.html.jsf.ExtendedHtmlLinkRenderer</renderer-class>
</renderer>
fur sure, only if you didnt use JSF-RI.
Ciao,
