I'm using the eclipse editor and changing the type of the gateway to a discriminator and get this "Join node 'Gateway' has no type" error

Changing it back to XOR or AND wouldnt help but if i get this right, using discriminator (/complexGateway) is just not possible atm?

This is a simple process where i get this error too:
