[ikostenko]

Edit any entry in "Orders" domain > De-select "Billing Address":

Expected result: an entry is saved, no value is shown for "Billing Address" field

Actual result: an alert is shown with the following message: "Array index out of range: 1". No exceptions in console

Non-optional associations still have to be marked as @NotNull as EntityManager does not throw any exception when nulls are set for such attributes and merged into persistence context. We probably need our own validation schema for handling those cases where JSR-303 is not in use.
