I everybody. I use JDeveloper 12.2.1.3. I have two jsff files. One of them includes a master table and the other one includes detail table. In one jsp page i dragged them as a region. My problem is if i select i master data. It does no change in the detail table. I set the detail region's partial trigger to master region. But it does not worked. Also when i try to create a new record in the detail table. It gives me "Parent key not found" error.
