Support for throwing messages?

[var-const]

Hi everyone,

Reading user guide, I noticed that Activiti has very little support for throwing messages:
- throwing message events are not supported;
- send tasks are not supported.
It seems that the only way to throw a message is to do so programmatically (correct me if I'm wrong here). So my questions are:
- why are these features unsupported? Is there some deep technical reason why this is very hard to implement? Note that I've seen questions about this going back to 2010;
- is there any plan to add support for those?

Anyone?

Hi var-const!
As far as I understand, there is no asynchronous mechanics for message/signal payload delivery in activiti engine. You can use synchronous signals with payload (process variables) as workaround (receiving process can become asynchronous next step after signal catching, so calling process will not be blocked).
Why do you need message throwing?
