custom renderer problem

Hi:
I am trying to create a component, a renderer and a tag for such a component.

I am having troubles connecting the renderer. In the getRendererType() method of the UIComponentTag if I return null everything works fine although ofcourse my renderer is not used. Now if I return the renderer type specified in <renderer-type> of the faces-config then I get a NullPointerException.
java.lang.NullPointerException at javax.faces.component.UIComponentBase.encodeBegin(UIComponentBase.java:676)
at javax.faces.webapp.UIComponentTag.encodeBegin(UIComponentTag.java:574)
at javax.faces.webapp.UIComponentTag.doStartTag(UIComponentTag.java:461)
at org.apache.jsp._test._jspService(_test.java:472)

Any ideas?

Thanks

OK, I found the problem. I need the method getFamily() in the component.

Thanks
