In JSON data that I want to import there is an element "bbox":[5.144448,52.068398,5.166034,52.084428] that I would like to map to an entity with four attributes: left, bottom, right, top. I cannot change the JSON format. I know that there will be four values in the array. Can I do this directly in the import mapping? Or can the import mapping only map to a set of values (decimals) and should I convert it afterwards? In the latter case it is important that the order in which the values are received is maintained. That seems not to be guaranteed (“ but the order of Mendix objects in the database may differ from the order of incoming XML elements.”, says the documentation).
