Description
From the spec: https://github.com/serverlessworkflow/specification/blob/0.8.x/specification.md#Action-data-filters
Each referenced workflow receives the SubFlow actions data as workflow data input.
In the attached reproducer, a forEach state triggers a subFlow.
Foreach definition includes iterationParam: name of the iteration parameter that can be referenced in actions/workflow. For each parallel iteration, this param should contain an unique element of the inputCollection array.
So far, the action data contains the collection item mapped with the param name.
In the reproducer, I expect that for each iteration the action data contains an element of names assigned to name, then the subflow is triggered with name initialized accordingly.
Step to reproduce:
1. Trigger the parent process with the following command
curl -X POST -H 'Content-Type:application/json' -H 'Accept:application/json' -d '{ "workflowdata": { "names": ["Donato", "Rachid"]}}' http://localhost:8080/foreach_parent
2. From the log it's possible to see that the subflow contains the parent data but not the action data:
2022-12-06 15:17:04,248 INFO [org.kie.kog.ser.wor.dev.DevModeServerlessWorkflowLogger] (executor-thread-0) Starting workflow 'foreach_child' (94a557ca-848f-4665-93ce-9511e0f8f9b1) 2022-12-06 15:17:04,248 INFO [org.kie.kog.ser.wor.dev.DevModeServerlessWorkflowLogger] (executor-thread-0) Workflow data { "names" : [ "Donato", "Rachid" ] }
Another suspect message in the log:
