 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).
