Answer 1

You are conceptually wrong. A query-based VO does not insert/update/delete any data to DB. You must create an entity-based VO if you want to insert/update/delete data to DB.
When you issue a commit operation on an AM, it looks for created/modified/removed Entity objects and then performs the corresponding DML operations on DB. (In fact, DML operations are performed by Entity objects. If there are no Entity objects, then there are no DML operations). If your VO is not entity-based (but query-based), then you do not have any created/modified/removed ADF entities, so there is noting to flush to DB.
The "Updateable" property of the VO attributes controls whether the VO should allow data entry/modification of these attributes in memory. You can have non-entity based attributes that are marked as "updateable" (for example, transient attributes storing temporary values in memory) but it does not mean that these attributes are going to be flushed to DB.
You have seen data in the read-only table, because it is based on the same VO and it displays the newly-created row which is in memory.
