JDev 11.2.1 Commit button does not save data

Question

I am using JDeveloper 11.1.2. I am having trouble saving updates to the database. I am trying to create an application that displays database records in a form, allows the user to modify data in the form and them saves that data to the database. I have successfully created the database, entity objects, view objects and application module. I created the form on the page by dragging the data control on to the page. I used the same method to create a table from the same data control. I included a submit button on the form. I dragged the create, delete and commit buttons onto the form. This application gets the data from the database, the user modifies it, select the submit button. This displays the change in the table. I can do the same with create and delete. However, I use the commit button to write the data to the database but it never happens. I have set up logging with –Djbo.debugoutput=console. I can see that the delete button {#bindings.Commit1.execute} is doing something but no change is made to the database.
Thanks for your help, Steve

I have had some success. I tested with the BC browser in my application and got the same results, no update. So I created a new application. I used the 'Create Business Components from Tables' option to create a set of Entity objects, Entity View objects, and Query View objects. The interesting thing I found was that when running the BC browser and trying to update the database using an Entity View object I had success. Was able to add and modify records and results saved in db. However, when I use the browser and try to do the same thing using a Query View object I get the behavior I've been seeing all along, it looks like it is working but not data saved to the database. In order to make the Query View object updatable in the browser I had to make all of its attributes updatable 'Always'. this made the view look updatable in the browser but no save. In my real application I did not have any Entity View objects. the Query View objects look the same so I didn't create any Entity View objects. So I want back to my real application, removed all Entity objects and Query View objects, recreated them with the 'Create Business Components from Tables' option. I created Entity View objects this time. When I drat a data control based on an Entity View onto my page I can make updates and the commit works.
I'd like to understand the difference between the Entity View objects and the Query View objects. Once they have been created I have a hard time telling them apart. The Entity View object for the Employee looks very much like the Query View object for Employee. There are some flags set differently and the Entity View object 'Entity Objects' tab shows the Employee table selected. I can tweek the Query View to look like the Entity View but it still does not behave the same, the commit does not save data.
