Renat, Is there any reason why Mistral do not pass action context such as workflow ID, execution ID, task ID, and etc to all of the action executions? I think it makes a lot of sense for that information to be made available by default. The action can then decide what to do with the information. It doesn't require a special signature in the __init__ method of the Action classes. What do you think? Thanks. Winson -------------- next part -------------- An HTML attachment was scrubbed...
