Tapestry 4 upgrade problem, nested link

I have a component that contains a component that contains a link component.
After upgrading to T4, I get the following error when I access the page by
submitting a form on the previous page, and running cycle.activate() on the
page (The url in the browser becomes  /SurveyEdit,form.sdirect):

Component SurveyEdit/viewQuestionnaireLink.link requires rendering support,
but no PageRenderSupport object has been stored into the request cycle. This
object is typically provided by a Body component. You should add a Body
component to your template.

When I access the page using the reset url, /SurveyParticipants.reset, the
page renders.... I have a Body component wrapping all the other components.

Thanks

Inge

Thanks, that's probably it, sounds logical!

I had a similar problem with PopupLinkRenderer. The issue is logged as
http://issues.apache.org/jira/browse/TAPESTRY-774. I used the proposed 
fix to create MyPopupLinkRenderer which overrides the constructURL 
method and checks for the rewind phase:

=========================
import org.apache.tapestry.contrib.link.PopupLinkRenderer;
import org.apache.tapestry.components.ILinkComponent;
import org.apache.tapestry.IRequestCycle;

public class MyPopupLinkRenderer extends PopupLinkRenderer
{
     public String constructURL(ILinkComponent link, IRequestCycle cycle)
     {
         if (cycle.isRewinding()) {
             return null;
         }
         return super.constructURL(link, cycle);
     }
}

=========================
Try this approach with your link component. It may help out.
