OK, next try…
If you qualify in memory, you may use the key "self" with an equals operator.
ERXQ.notEquals("self", studentToRemove);
If you qualify in database, I found a working solution. Add a method to your
entity class that return a qualifier like this:
public ERXKeyValueQualifier notMeQualifier() {
return ERXQ.notEquals("id",
ERXEOControlUtilities.primaryKeyObjectForObject(this));
}
"id" need to be replaced by your primary key attribute name, this attribute
does not need to be visible (class attribute) and this will only work for
single column primary key.
