How to trigger a Sub flow using "Signal Event" which is getting generated in Parent Flow ?

[sushant]

Issue - At step 3, Subflow is not getting called in spite of configuration. Please provide any pointers. I do not want to call this child flow from  parent flow like below :

Hey Sushant,

I am still trying to work out why the Signal is not being picked up.

But since you are calling the signal task from a Listener, I found a work around.

Rather than using a signal start event. Just use a regular start event.

Then, instead of sending the signal, simply start the sub process from the runtimeService using startProcessInstanceByKeyAndTenantId().

I have attached an updated project with the work around implemented.
Agreed, I dont like it and we need to work out why signals are not working in this scenario, but it shoudl get you moving.

Sushant, I spoke too soon.

The solution is actually very simple and is because it appears you are using Enterprise Edition rather than community edition.

You cannot call runtimeService.signalEventReceived() to trigger a signal start even in Enterprise edition UNLESS the process was deployed without a tenant id. By default, all deployments will include a tenant ID and the signalEventReceived includes the tenant ID in the query to locate subscriptions.

SO, ALL YOU NEED TO DO IS CHANGE YOUR RUNTIMESERVICE() CALL TO :

runtimeService.signalEventReceivedWithTenantId("EMAIL_SUPPORT_SIGNAL", "tenant_1");

Obviously if you are part of a different tenant, you would include that id.

I tested this and it worked immediately.
