the definition with different name
>return workflow_instances.uniq
to gets the different instance id
then
ArWorkitem.find(:all,:conditions => ["wfid in
(?)",get_histoy(expression,workflow_instances = [])])
gets all workitems of one subprocess hava applied,
use HistoryEntry has to sort by the column "fei",it is a long string ^_^
>b) return the list of subprocess instances for a given main process
instance ?
right
is there other way to get the history?
