ADF data table - posting changes without row change

Question

Hi,
I’m using JDevloper 11.1.2.3.0 to build a master detail page (for ex, departments and employees) where both master and detail are editable. So, I dragged and dropped the master data control (departments) on the page as an ADF table. Then I dragged and dropped the detail data control (employees) on the page as an ADF table (the detail control is the one inside the master data control). Each table is inside a panelCollection.
At run time, the page displays fine and when I change the selected row in the master, the detail table changes correctly.
In the toolbar of each panelCollection, I added:
•     The createInsert operation of the corresponding data control.
•     A “save changes” button to commit the changes: the button is not the commit action of the module but instead it is a toolbar button linked to a method in the bean that execute the commit operation (using the bindings) and then reload the master data control (both master and detail buttons points to the same action).
This is also working: if I change a field in the master table or create a new row and click the “save changes” button of the master table the changes are correctly posted. Same for the detail table if I change a field in the detail table or create a new row and click the “save changes” button of the detail table the changes are posted.
The problem is when I add a row in the detail table for ex and click the “save changes” button of the master table (without changing the selected row in the detail), the changes are not committed. Same happen if I create a new row in the master table and clicked the “save changes” button of the detail table (also without changing the selected row in the master).
It seems that the problem is that the table is not posting the changes when I directly click the “save changes” button of the "other table". If after adding a new row, I change the selected row before clicking the “save changes” button data is correctly saved whatever “save changes button” is clicked.
So how can I make the table post the changes is this case?
Or should I make the “save changes” button of the master table for ex disabled when I change something in the detail table and vice versa? (If yes how? The disabled property of the “save changes” buttons is currently: #{!bindings.Commit.enabled})
Or should I have only one “save changes” button that saves all the changes on the page?
Or …
Is there any useful link i can check?
Thank you.
