Working with XML > relational importer, there could be relational objects with names containing a colon ':' character.
Renaming an object in the diagram results in the characters after and including the colon to be dropped. This is a fault of the rename action that is looking for possible datatypes defined during the rename action (i.e. user could type "firstName : string(255)") and designer will set the datatype to "string" and the "length" to 255.
Probably need to look for the "Last" colon, determine if the "last" segement IS a valid datatype. If it is, parse the last segment as D-type. if NOT, then set the whole input string as the object's name.
