I am running into a issue while trying to map a CDT to a Database view. Background is ,we had a view which selects records by joining multiple tables. While defining the CDT we had defined one of the columns with @Id JPA Annotations. Everything worked fine ,but as part of an ongoing enhancement we changed the view to have an additional table. When joining with this table ,the column which had @Id is no more unique ,it has duplicate values. We are using a query entity to return data from this view ,but with this @Id having duplicate values ,"totalCount" returned takes only the distinct values of this ID. This in-turn mess up our Grid ; I tried making composite primary key by defining some additional columns with @Id. It is also not working ,possibly because those columns are VARCHAR

It's also possible to do the same thing with row numbering or generating keys by concatenating values (as you've tried), but I've found UUID() reliable as it should guarantee a unique ID for each row regardless of data.
