Class::Workflow::Instance::Simple - A Workflow instance objects to work with the other ::Simple classes.
use Class::Workflow::Instance::Simple; my $i = Class::Workflow::Instance::Simple->new; my $new_i = $transition->apply( $i );
This method adds an error field to Class::Workflow::Instance.
In the event that you want to make errors non-fatal, but instead encapsulate errors in the workflow using their own states,
error just becomes a regular field. Class::Workflow::Transition::Validate::Simple provides a simple means to add validation, with the optional notion of an
error_state for transitions.
Does what it says.
