WAS 6.40 sneak preview and portal iview development

Hi,

I was installed WAS 6.40 developer edition sneak preview. Its included portal application wizard. Is this correct wizard? I'm tried creating one portal appl. But created Dynapage source class is extended PageProcessorComponent.

there is error reported developer studio.

error is "PageProcessorComponent is not resolved or is not a valid superclass".

Wat's the problem?

Thanks.
