External Mapping of Node ... is not completed yet

Hi there,

I have the follwing situation:

I created an interface node within a web dynpro interface and marked it as Input Element (Ext.) = true.

After that I implement this interface in a web dynpro component. When I try to start the application I retrieve the following error:

<b>External Mapping of Node ZAN_CHILD_COMP1#COMPONENTCONTROLLER.CONTEXT.MODE Is Not Completed Yet</b>

Can anybody help?

Kind regards,

Albert
