Call activity calling process with message start events

[hassang]

Hi @Jennie,

Call activity works with none start event only.

To start a process by message use a message intermediate throw event instead. Below post contains an example with implementation set to Expression

Call activity should not wait for called process completion in the main process is that possible

Hi @venky1982, You can set implementation to Expression and use an expression similar to below example expression to start a process by message “message_invoiceReceived”. #{execution.getProcessEngineServices().getRuntimeService().createMessageCorrelation('message_invoiceReceived').setVariable("invoiceId", "123456").correlate()} [image]

But keep in mind that using message intermediate throw event will continue execution of the calling process and won’t wait until the end of the called process as with “Call Activity” so if the need is to wait then a message intermediate catch event should follow the message intermediate throw event in the calling process & a message end event should be used in the called process.
