Dear Jason,
This is a nice piece of work! I have thought about the "wizard" problem
many times, but I never addressed it in a structural way. I'm delighted
to see that you took the first step. Therefore I'd like to express my
thoughts about wizards:
I define workflow as a finite tree of process steps (nodes) and a wizard
as a manager of workflow with the following properties:
1) It evaluates the values that an agent submitted in each process step
to decide what the next step in the tree will be;
2) It remembers the path through all previous process steps and the
corresponding submitted data for those steps;
3) It executes a persistent transaction when an agent committed the leaf
step in the tree.
The first property is partially satisfied in the current Phrame release:
an ActionForm validates the quality of submitted data and the
corresponding Action forwards the controller to the next step based on
that data. The mappings file is currently missing the syntactic sugar to
easily move backwards in the process tree: one should define a forward
to every child for a given parent and one should define a forward to
every parent for a given child.
In my opinion your code could be a good starting point to address the
second and third property of a wizard. I'm very interested in other
opinions this subject!
Kind regards,
Bas
