Hey Ramsey,

So, this really helped me out. I knew I was being stupid. I didn't know you had to pass the WOComponentContent into the WOSwitchComponent.

Don't sweat it. Even Chuck admitted to finding woswitch and wocomponentcontent confusing (^_^) And he's always right. So they are confusing. I found the diagram from the D2W guide extremely helpful in understanding them though.

Look at figure 2-1. Notice how the yellow page component is the root element. The PageWrapper is like a picture frame, and the WOComponentContent is the hole in it. Its parent() is the yellow page. In fact, all the grey boxes in that diagram are WOSwitchComponents. MenuHeader is a 'regular' wocomponent and it is placed in the PageWrapper by hard coding the name in the PageWrapper.wod. Switches on the other hand are placed in the page by dynamically setting the WOComponentName binding at runtime.

Otherwise, switches work the same as regular wocomponents. Passing a binding to a switch passes the binding directly thru to the named component at runtime. If a switch component has component content, then whatever you wrap the switch around shows through the hole.

Using ERXD2WList, however, I still get this output in the log
