List output iteration

[lexiismadd]

Is there a way to iterate over the list output from an action, but performing multiple actions on each list item.

so for example, the result from Action A is a list.
I was Action B, Action C, and Action D to iterate over each list item.

Then maybe the output from Action D is another list, and I want Action E and Action F to iterate over the output from Action D (which is still in the loop iterating over the output of Action A)

Is this possible?

Yes. You have to use additional workflows to group the actions. Workflow1 would call ActionA and Workflow2. Workflow2 would group B, C, D and Workflow3. Workflow3 would group E and F. Execution would be conceptually like the below graph:

Workflow1
  -> ActionA [output: list1]
  -> Workflow2 [with-items: list1]
    -> ActionB
    -> ActionC
    -> ActionD [output: list2]
    -> Workflow3 [with-items: list2]
      -> ActionE
      -> ActionF

Keep in mind Orquesta with-items does not behave like common programming loops. It only applies to a single action or workflow. The iterated value is only available as a variable to the invoked action using item() and is not available in the next: section of the action definition. The results keyword will contain the list of results returned by the execution of each action.
