Property :: unlockInstance - Unlock instance

The function is used in order to unlock the instance referenced by the property handle previously locked with lockInstance() . Instances for shared base structures are not automatically included in unlocking and must be unlocked explicitly when being locked separately.

The function throws an exception, when the property does not handle a collection or when unlocking the instance failed (e.g. no instance selected, instance not locked or locked by another application). Any attempt to unlock non-persistent instance will throw an exception, too.
