DOMOBJECT:get_data( key [, key2, ...] )
Gets one or more values from the data manager. Each argument to the function should be a key relative to the DOMOBJECT. The keys are fully qualified before being used as a data manager key whose value should be extracted from the data manager. This function returns a table using all the keys as indexes and the corresponding value is the data returned from the data manager. A nil is returned for any values that do not match a key in the data manager.
Parameters:
key A relative key, to be fully qualified in the context of this DOMOBJECT.
Returns:
A table containing the passed in arguments as keys and the resulting data manager values as
the values associated with those keys.
