Review comment:
if the `Update Keys` property is not set, then `updateKeys` is `null`, not
an empty string as is set in the unit tests. This causes a NullPointerException
where the update keys are split from the property value. A null check should be
added, either to set the field to the empty string or to throw a different
exception than NPE. This can/should also be done in `customValidate`, which
illustrates the need for custom validation code (albeit duplicated at times).
