Hello All

I'm still stuck getting inheritance working properly in Cinderella so much so
that I've tried to recreate the problem shown in the Text book by Laurent
Doldi. I've used the model on pages 106 & 107 and as far as I can see I have
entered the data as per the book.

I get a set of error messages

1. Entity is also defined in supertype
2. No connection to gate rc for this type based instance
3. No connection to gate g1 for this type based instance
4. A receiver for sccp cannot be reached form this process.

It seems to me that it is all tied up with the inheritance the block protocol
by SS7. In the book it states that the entity [manager] is dashed because it
already exists in the supertype protocol. I feel that if had defined the
inheritance properly I would not have this problem, but without getting beyond this
step I'm not going to progress any further.

Has any one any ideas where I'm going wrong. My diagrams all look the same as
the text book except the instance of the redefined manger.
