Hi everyone,

I'm working with Symfony's Workflow component (type: workflow, not state_machine) and have a situation where I need to apply multiple transitions from the same place, but I'm facing a conflict with how markings are managed.

Context

I'm modeling a complex amendment workflow. All amendment types (TYPE_1, TYPE_2) branch out from the same place: consolidation_final_check.

Each amendment transition starts from this shared place. For example:

to_type_1:
  from: consolidation_final_check
  to: [classification_type_1, impact_assessment, consolidation_final_check] # I preserve the place

to_type_2:
  from: consolidation_final_check
  to: [fill_field_ah_entity, consolidation_final_check]

This allows me to apply multiple amendment transitions in parallel, because consolidation_final_check remains in the marking.

However, I run into issues when I move forward in one flow.

The Problem

Consider this transition:

type_2_to_consolidation_final_sign_go_dev:
  from: [classification_type_1, impact_assessment, consolidation_final_check]
  to: consolidation_final_sign_go_dev

When I apply it:

• consolidation_final_check is removed from the marking (because it's in from: but not in to:).
• This breaks other transitions (like to_type_2), which still need consolidation_final_check in their from: list.

So effectively, once I commit to one flow, the other amendment branches become inaccessible — even though they haven't been used yet.

What I’m Trying to Achieve

I want to:

• Start multiple amendment transitions from the same place (consolidation_final_check)
• Progress through each amendment flow independently
• Keep consolidation_final_check in the marking as long as it's needed by other flows (or via another method if it exists)

Possible Solution?

I’ve started doing this:

type_1_to_consolidation_final_sign_go_dev:
  from: [classification_type_1, impact_assessment, consolidation_final_check]
  to: [consolidation_final_sign_go_dev, consolidation_final_check]

This seems to work, since it preserves consolidation_final_check, allowing other transitions to still function. But doesn't seems to be clean as I don't want to alway keep this consolidation_final_check in all transitions...

Questions

1. Is this the correct/clean way to handle parallel branches in Symfony workflows?
2. Is there a better or more idiomatic pattern to model this kind of situation?
3. Should I be using a different design?

Thanks in advance for your help!
