[Perl-workflow-devel] How to get a workflow's possible states?

[Phil R. <phi...@un...>]

Hi all
Does anyone know if there's a way to get a list of all the possible 
states a workflow could have?

My app. creates lots of workflows for 'jobs', and can display them in 
lists. I want to have a
way where the user can select which ones they see based on their state.

So I need a menu where the user can select for display (eg) INITIAL, 
ORDERED, PROCESSED,
FINISHED, DESPATCHED. Of course, I could hardcode it but I'd really like 
to be able to
change the workflow without having to change the code too.

The only thing I can think of is to create a test workflow, get the 
initial actions and then recursively
run all the actions, gathering up all the states I pass though them, It 
would be a nightmare
though as there are lots of conditions etc.

Come to think of it I could read and parse the xml workflow definition 
which would be simpler.

Any better ideas? TIA Cheers, Phil
