> When running as a portlet, there is no way to generate a link during the processAction() phase, that is the rewind phase.
> When a Link component attempts to render its link during rewind, the PortletLinkFactoryImpl crashes because _renderResponse is null.
> One solution is to change the renderComponent() method of AbstractLinkComponent:
>      protected void renderComponent(IMarkupWriter writer, IRequestCycle cycle)
>      {
> +    	if (cycle.isRewinding())
> +    		return;
>          getRenderer().renderLink(writer, cycle, this);
>      }
> Not quite sure about the side effects...
