JBO-35007 - Where is it when you need one?

Question

Project details: Jdev 10.1.3.3, ADF BC, ADF Faces
Please help me to understand when I can rely on JBO-35007.
I have a pretty simple use case:
1. List employees in a table with selection
2. Select an employee and navigate to the edit page. Edit page has 2 buttons - "Commit" and "Back To List". "Back To List" button executes global navigation action
Now where the fun part starts.
1. User goes to the 'listEmployees' page, selects a row in a table, then presses "Edit" button - he is taken to the 'editEmployee' page.
2. User presses CTRL+N to create a new window (I know they are not supposed to do that, but they do!).
3. While being in the new window user presses "Back To List" button and as expected is taken to the 'listEmployees' page.
4. Here user navigates to a different row, then selects 'editEmployee' button.
Right after this user switches back to the previous window (Remember that the previous window is still showing the old record from the step 1 above)
5. User modifies one or more fields and presses "Commit"
At this moment the famous JBO-35007 is displayed as expected, and this is a good thing. I expect the same error to be displayed the next time user presses the "Commit" button, but it does not!
Instead the record from the step 4 above is being updated.
Now my question is - Is this an expected behavior? If yes, how do I prevent user from executing "Commit" second time?
Thank you,
Vitaliy

I'll do my best. Please note that this is code I'm writing off the cuff; it's intended as an outline, not necessarily as something that will work in a cut-and-paste.
public void reportErrors(PageLifecycleContext context)  {
    super.reportErrors(context);
    RegionBinding bindings = context.getBindingContainer();
    List runtimeErrors = ((DCBindingContainer) bindings).getExceptionsList();
    for (Object e : runtimeErrors) {
        if (e instanceof InvalidOperException) {
            InvalidOperException invOper = (InvalidOperException) e;
            if (invOper.getErrorCode()="JBO-35007") {
                Key expectedKey = (Key) invOper.getDetails()[0];
                RowSetIterator it = (RowSetIterator) invOper.getSource();
                Row[] matchingRows = it.findByKey(expectedKey, 1);
                if (matchingRows.length > 0) {
                    it.setCurrentRow(matchingRows[0]);
}
