- DataMapper is not able to handle structural mis-matches easily. In the case of getBasket, we have our List of Maps retrieved from the Database and we need to create an Xml document according to the WSDL Schema. However, given that each Item has many Images and it's convenient for us to retrieve all in the one ResultSet, we need to de-duplicate the repeating Item data. We do this in MEL and we create a Map of data which is structurally similar to the target XML in order to give DataMapper a helping hand!
