Call a method before Next operation to set selected values

Question

Use Case: I display a VO as a ADF Select Many Check Box. This VO is the detail of a master/detail. I managed to store the selection state in a managed bean on autoSubmit. Then the user navigate to the next master record, then goes back to the previous record. The Previous and Next buttons were created using the Operations in the data controls. I would like to put back the selection state when clicking on Previous or Next.
There is plenty of tutorial on how to get the selected values, but none on how to set the selected values. How would you do it?

What I ended up doing:
1. Redefine action listener for the navigation buttons
    public void nextQuestion(ActionEvent event) {
        saveSelectedState();
        navigateQuestion("Next");
        restoreSelectedState();
    private void navigateQuestion(String operation) {
        OperationBinding operationBinding = ADFUtils.findOperation(operation);
        operationBinding.execute();
2. The save and restore selection state using bindings
     // Guava Multimap
    private ListMultimap<Number, Integer> selectedIndices;
    private void saveSelectedState() {
        // Get question id
        DCIteratorBinding questionBinding = ADFUtils.findIterator("QuestionsView1Iterator");
        Row question = questionBinding.getCurrentRow();
        Number questionId = (Number)question.getAttribute("Id");
        JUCtrlListBinding listBinding = (JUCtrlListBinding)ADFUtils.getBindingContainer().get("AnswersView2");
        int[] valueIndices = listBinding.getSelectedIndices();
        selectedIndices.putAll(questionId, Ints.asList(valueIndices));
    private void restoreSelectedState() {
        // Get question id
        DCIteratorBinding questionBinding = ADFUtils.findIterator("QuestionsView1Iterator");
        Row question = questionBinding.getCurrentRow();
        Number questionId = (Number)question.getAttribute("Id");
        int[] valueIndices = Ints.toArray(selectedIndices.get(questionId));
        JUCtrlListBinding listBinding = (JUCtrlListBinding)ADFUtils.getBindingContainer().get("AnswersView2");
        listBinding.setSelectedIndices(valueIndices);
