i trying use direct binding on following stream.

stream create --definition "time | log" --name ticktock stream deploy ticktock --properties module.*.count=0 

deployment fails exception on both admin , container node:

i have spring-xd(1.2.0) cluster 1 admin , 2 container nodes using kafka message bus.

am doing wrong? or there problem direct binding , kafka message bus?

per the documentation, xd kafkamessagebus not support direct binding...

note: kafka message bus not support count=0 module deployments, , therefore, not support direct binding of modules. feature available in future release. in meantime, if direct communication between modules necessary kafka deployments, composite modules should used instead.
