Dear all,

I want to check if the outgoing connections name are different so I use the following OCL expression in the interactive OCL console:

self->isUnique(self.outgoingConnections.connectionName)

However, It always return true!!

Any Help or Suggestions?

Thanks in advance. Smile

Hi,

May be try something like:

self.outgoingConnections->isUnique(c:Connection|c.connectionName)

Not very familiar with OCL myself, but I think the problem is your OCL constraint is not constructed properly.

Hope this helps.
