Hi Ken,
Thanks for your response. Your idea works great, but the UI is still not updating. My WORepetition is bound to a WODisplayGroup and I am beginning to wonder if that is another factor complicating things. Have you used a WODisplayGroup and marked records for deletion? The code I am using is below. Maybe I am doing something wrong? Thanks,
David
public void appendToResponse(WOResponse aResponse, WOContext aContext) {
if (documentToUndelete != null) {
EOEditingContext ec = session().defaultEditingContext();
Integer i = new Integer(0);
documentToUndelete.takeValueForKey(i,"deleted");
DeletedLookup aDeletedLookup = (DeletedLookup)documentToUndelete.valueForKey("deletedLookup");
documentToUndelete.addObjectToBothSidesOfRelationshipWithKey(aDeletedLookup,"deletedLookup");
ec.saveChanges();
}
if (documentToDelete != null) {
EOEditingContext ec = session().defaultEditingContext();
Integer i = new Integer(1);
documentToDelete.takeValueForKey(i,"deleted");
DeletedLookup aDeletedLookup = (DeletedLookup)documentToDelete.valueForKey("deletedLookup");
documentToDelete.addObjectToBothSidesOfRelationshipWithKey(aDeletedLookup,"deletedLookup");
ec.saveChanges();
}
super.appendToResponse(aResponse,aContext);
}
public WOComponent deleteDocument()
{
documentToDelete=itemDocument;
return context().page();
}
public WOComponent undeleteDocument()
{
documentToUndelete=itemDocument;
return context().page();
}
// used to bind to the WOConditional
public boolean markedForDeletion()
{
DeletedLookup aDeletedLookup = (DeletedLookup) valueForKeyPath("itemDocument.deletedLookup");
String deletedFlag = (String)aDeletedLookup.deleted_desc();
return deletedFlag.equals(thisIsMarked);
}

Since you are directly modifying an attribute that is determining the structure of the page, things are getting messed up (WO doesn't like this). What I usually do is have the hyperlink put the record to modify into a temporary variable (or something), then update the EO's flag in appendToResponse(). Something like this (just pseudocode here)
public WOComponent flipDeletedFlag() {
recordToDelete = currentRecord;
return context().page();
}
public void appendToResponse(WOResponse aResponse, WOContext aContext) {
if (recordToDelete != null) {
recordToDelete.setDeleted(true);
recordToDelete = null;
super.appendToReponse(aResponse, aContext);
}

I have a conditional that wraps a hyperlink for marking documents for deletion. The binding is set to the value of the deletion flag.
If a document has already been marked, the hyperlink allows an "undelete" and resets the flag. Clicking the link changes the underlying variable, but it doesn't immediately affect the WOConditional until I log out and then log back in. What am I doing wrong?
