Composite Key Updates Fail

[valhuber]

In classicmodels, OrderDetails cannot be updated due to primary key of Order & Product IDs.

Setup is Step I of this page: https://apilogicserver.github.io/Docs/DevOps-Containers-Deploy-Multi/

Then, just update an OrderDetail

The default delimiter for a composite pk is "_", this can be overriden by setting SAFRSBase._s_pk_delimiter to something else (for example "|" ).

Could you try this please?
