[daisy] Configuring workflow tasks programmatically

[Paul Focke]

Hi Ross

You are describing quite a few different processes here.

I guess its a matter of preference but I'd go for your B option, each
step would have a different task node. Why this? Well when you are at
the start of your process instance you'd want to proceed to the
'prepare' step. So you have 1 transition to the 'prepare' node which
only has one task. The prepare task node only has 1 transition to the
next task node and so on. This way you simply transition your way
through the process and the users get bit sized tasks to do. Also in the
UI the actions a user can take in the bottom of a screen are transitions
to another node in the graph.

For the 'review each team member' process. You could go for the simple
solution and define the team in a pool. The team would the just have to
use a certain notation and place all the reviews in one variable. The
other way would be to indeed have a dynamic process definition but I
haven't had any experience with this. Maybe there is something on the
jBPM list that could be of help. However you'd also want the daisy meta
data to be dynamic as well but I don't think that is possible (bruno?).
So you'd have to have enough 'generic' definitions in the meta data to
cope with dynamic nature of the definition.
