[Seaside] popupAnchor in Seaside 2.6

[Rick Zaccone]

If I want to create a popup anchor in Seaside 2.6, I need to do  
something like this:

renderContentOn: html
     html popupAnchor
         url: 'http:/www.amazon.com';
         name: 'foo';
         extent: 400 @ 350;
         with: 'Amazon'

If I leave out the name, I get a walkback.  Why is the name  
necessary?  I didn't need it in Seaside 2.5.  It took a bit of poking  
around to figure out what was wrong.
