Class ERDObjectSaveDelegate

java.lang.Object
  er.directtoweb.ERDObjectSaveDelegate

public class ERDObjectSaveDelegate
extends java.lang.Object

Simple com.webobjects.directtoweb.NextPageDelegate implementation that saves the editing context of an enterprise object before returning the next page. This can be particularly handy for example if you want a user to confirm an action before the editing context is committed, for example:
Assume that you have a User object that has been editinged in a peer context and now you want the user to confirm that they really should save the changes to the editing context, you could have this method:
public WOComponent confirmSave() { ConfirmPageInterface cpi = (ConfirmPageInterface)D2W.factory().pageForConfigurationNamed("ConfirmSaveUserChanges", session()); cpi.setConfirmDelegate(new ERXObjectSaveDelegate(user, context().page())); cpi.setCancelDelegate(someCancelDelegate); return (WOComponent)cpi; } This way if the user selects the confirm button the editing context will be saved and they will be brought back to the current page.
