[D2W] Using a custom component inside ermodernlook

Hello everybody,

I'm yet again stuck with a D2W/ERModernLook Issue. 
I am trying to add a normal component to my D2W project by following this little how to:
http://wiki.wocommunity.org/display/documentation/Adding+a+Normal+WOComponent+Page+to+an+ERModernLook+based+application

I have managed to create and edit everything according to the tutorial, but unfortunately I still get this error:

java.lang.IllegalStateException: 
Couldn't find the dynamic page named com.mycompany.adminD2W.ui.components.payment.Payment in your DirectToWeb model.task and entity is null, it seems that one model, maybe ERDirectToWeb d2w.d2wmodel is not loaded!

I think it has to do with the extra rules that had to be adder to make it work:
pageConfiguration = 'Payment' => entity = "ActivePayment" [WO:com.webobjects.directtoweb.EntityAssignment]
pageConfiguration = 'Payment' => task = "QueryAll" [WO:com.webobjects.directtoweb.Assignment]
pageConfiguration = 'Payment' => templateNameForInspectPage = "Payment" [WO:com.webobjects.directtoweb.Assignment]
pageConfiguration = 'Payment' => navigationState = "Payment" [WO:com.webobjects.directtoweb.Assignment]

Especially this one looks fishy:
pageConfiguration = 'Payment' => entity = "ActivePayment" [WO:com.webobjects.directtoweb.EntityAssignment]

When I open the rule editor is shown as a com.webobjects.directtoweb.Assignment:

If I open it with a text editor instead I can clearly see the EntityAssignment class in the rule:


What could I possibly be doing wrong here? Is this even the right way to add a non D2W Component to the ERModernLook?

Any Help is appreciated :)

Greetings Carlo
