If you use the SPLIT in a default expression on an multivalued attribute, please note that the result will be stored as collection, meaning that all duplicates will be removed. To illustrate this: suppose we have an attribute Test.Splitted (multivalued), which has the default expression SPLIT ( "H.E.L.L.O" , "\.") . The result of the expression JOIN ( Test.Splitted , "" ) = "HELO" instead of "HELLO" as in the last example. |
