Hi,

The source code in er.extensions.ERXGenericRecord.isDeletedEO() in

// 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);
}
Well, there is a bug in this method, because if the editing context is
null, it still return false, unlike said in the JavaDoc... And the
result of the multiple "editingContext()" can even change...
The code would better be like this:
public boolean isDeletedEO() {
EOEditingContext editingContext;
editingContext = editingContext();
if(log.isDebugEnabled()) {
log.debug("editingContext = " + editingContext + " this
object: " + this);
}
return((editingContext == null) ||
editingContext.deletedObjects().containsObject(this));
}
Kind regards,
