Communication between processes

Hi everybody.

I am quite new to Activiti and have a simple question regarding the communication between different processes and did not find an answer anywhere.

I am using the Eclipse Plugin (Eclipse Designer). So, I have a simple process that should send a "signal" at a certain point in the process. Another process should wait for that event, catch the "signal" and react to it. The processes are on the same level, so no sub-process.

The problem is, a signal in Activiti is a broadcast and will be caught by all active process instances. A message would be the solution, but I found out that there is no "Message Throw Event". What I am looking for is a signal element comparable to the signal event in UML 2.0.  So, are there any options how to model the processes without needing to use external services too much?

Thanks in advance.
