[gme-users] Constraining connections to 0..1

[Gabriele Trombetti]

Hi all,
there is a thing I don't understand in GME. We have a metamodel where 
there are components and ports. There are some ports that can connect 
only to at most one other port. So we have put the cardinality of such 
connections to 0..1 both before and after the connector dot in the 
metamodel.

But in the instance models, we still can create connections from one of 
such source port to *two* other ports, so that *two* separate 
connections get created from the same source, ending in the two separate 
destinations. So what is the purpose of the cardinality spec in the 
metamodel??

Thanks in advance
Gabriele
