You can set-up workflow using D2W.
For instance, this is a sample D2W workflow that takes an appointment (one
of my EOs), sends the user to an edit page. When that is saved, it runs the
delegate below.
/**
* Edits (usually a newly created) encounter showing a D2W edit page to
complete the core details
* and then a more complex custom edit page allowing full editing.
*
* @param e
* @param returnPage
* @return
*/
public static WOActionResults editEncounterInTwoSteps(Appointment a,
WOComponent returnPage) {
EditPageInterface nextPage = (EditPageInterface)
D2W.factory().pageForConfigurationNamed("EditAppointment",
returnPage.session());
nextPage.setObject(a);
nextPage.setNextPageDelegate(new SaveOrCancelDelegate(returnPage));
return (WOActionResults) nextPage;
}
/**
* A simple NextPageDelegate that understands whether an object was saved
or not and
* chooses the appropriate next page (ie to a next page or to a cancel page)
* @author mark
*
*/
public static class SaveOrCancelDelegate implements NextPageDelegate {
private WOComponent _cancelPage;
public SaveOrCancelDelegate(WOComponent cancelPage) {
_cancelPage = cancelPage;
}
public WOComponent nextPage(WOComponent sender) {
ERDObjectSaverInterface epi = (ERDObjectSaverInterface) sender;
if (epi.objectWasSaved() == true) {
Appointment a = (Appointment) ((ERDEditPageInterface) sender).object();
if (a.isInFuture() == false) {
EditEncounter editPage =
ERXApplication.erxApplication().pageWithName(EditEncounter.class);
Encounter e =
a.createEncounterForAppointment(((User)ERCoreBusinessLogic.actor()).localInstanceIn(a.editingContext()));
a.setOutcome(Appointment.Outcome.COMPLETED);
e.editingContext().saveChanges();
editPage.setEncounter(e);
editPage.setNextPage(_cancelPage);
return editPage;
}
}
return _cancelPage;
}
}
You can see that, if the appointment is not in the future, then an
encounter EO is also created and then the editing context saved again.
Good luck,
Best wishes,
Mark
