Erwin,
This may be what you are looking for to ‘flush’ out the old recordset and request a new one on reloading the page (force a fresh fetch).
session().defaultEditingContext().invalidateAllObjects();

sorry, could not find any hint in archives...
In my "ListContactPage", I display a list of Agent's contact entities in a WODisplayGroup (master "Agent"- details "contacts") works fine... (with 'fetches on load' option selected )
public ListContactPage(WOContext context) {
super(context);
this.takeValueForKeyPath(((Session) session()).agent(), "agentContactDisplayGroup.masterObject");
}
.......
then I select one contact to view the contact info in a "ContactDetailPage"
public WOComponent viewContactInfo(){
ContactDetailPage nextPage = (ContactDetailPage)pageWithName("ContactDetailPage");
nextPage.setTheContact(aContact);
return nextPage;
}
In my "ContactDetailPage" I can delete the displayed contact
public void setTheContact(EOEnterpriseObject aContact){
theContact = aContact;
}
public ListContactPage deleteContact(){
Agent contactAgent = ((Contact) theContact).agent();
contactAgent.removeObjectFromBothSidesOfRelationshipWithKey(theContact,"contacts");
EOEditingContext ec = session().defaultEditingContext();
try {
ec.deleteObject(theContact);
ec.saveChanges();
} catch (Exception e) {
ec.revert();
NSLog.err.appendln("An exception occurred while trying to remove a contact: " + e);
}
ListContactPage nextPage = (ListContactPage)pageWithName("ListContactPage");
return nextPage;
}
But when the ListContactPage redisplay, the deletec contact is still in the WODisplayGroup... i know it has been deleted from the database .. (if I restart the woapp, I don't get it anymore in teh WODisplayGroup...
si it seems to be a problem of doing a new fetch from the database, WODisplayGroup should do it itself on reload... ,,
