``AND``
With an ``AND`` mode, the activity will wait for all its incoming
transitions to be crossed before being run.
Kinds
'''''
Activities can be of different kinds: ``dummy``, ``function``, ``subflow``, or
``stopall``. The kind defines what type of work an activity can do.
Dummy
The ``dummy`` kind is for activities that do nothing (i.e. they act as hubs
to gather/dispatch transitions), or for activities that only call a Server
Action.
Function
The ``function`` kind is for activities that only need to run some Python
code, and possibly a Server Action.
Stop all
The ``stopall`` kind is for activities that will completely halt the
workflow instance. In addition they can also run some Python code.
Subflow
When the kind of the activity is ``subflow``, the activity will run
another workflow. When the sub-workflow is completed, the activity will also be
considered completed.
Normally the sub-workflow is instanciated for the same record as the parent
workflow. It is possible to change that default behavior by providing
Python code that has to return a record ID for which a workflow has been
instanciated.
