Getting a list of transitions for all workflows in an object's workflow chain

I have an object with two workflows.

obj.portal_workflow.getTransitionsFor(obj)

returns only transitions from the primary workflow.

I've written the开发者_StackOverflow following code to get a list of all possible transitions for all items in a list.

How am I doing?

transitions = []
for i, obj in enumerate(self.items):
    for w in workflow.getWorkflowsFor(obj):
        for tid,t in w.transitions.items():
            if w.isActionSupported(obj, tid):
                if t not in transitions:
                    transitions.append(t)
return transitions

For what I see in the getTransitionsFor source code, it must returns you all transition for all workflows.

What you have should work just fine. But you may want to consider using the method already available in @keul's answer.
