The source code in er.extensions.ERXGenericRecord.isDeletedEO() in
Project Wonder looks like this ....
/**
* Determines if this object is a deleted object by
* checking to see if it is included in the deletedObjects
* array of the editing context or if it's editing context
* is null.<br/>
* <br/>
* Note: An object that has just been created will also not
* have an editing context and by this method would test
* positive for being a deleted object.
* @return if the object is a deleted object
*/
// CHECKME: Might be able to tell better by checking EOGlobalIDs
public boolean isDeletedEO() {
if (log.isDebugEnabled())
log.debug("editingContext() = " + editingContext() + " this
object: " + this);
return editingContext() != null &&
editingContext().deletedObjects().containsObject(this);
}

Hi!
Imagine the following code (I'm writing this directly on the email,
it's possible that it contains errors):
EOEditingContext myContext = getMyContexy();
MyClass myObject =
giveMeSomeObjectOfMyClassSotredOnTheDataStorage(myContext);
myContext.deleteObject(myObject);
myContext.saveChanges();
Right after this, what exactly is myObject? Is there a way to know
that it references a previously deleted object? The only way I can
find is calling myObject.editingContext() and catch a
NullPointerException, but that method is very very dirty... is there a
better way?
