I have the problem when I bind the context of one DC(a) interface controler with the component of the other DC's component controler (b), then i get messages that the iprivate imports don't exist.
steps i take are:
1 Add components to public part
2 Build the DC
3 Add used DC into one DC
4 Add used component
5 bind the conext of comp a to interface b.
6 create the methods
