Hi Pedro,

Here it is.

So, I basically move the question up or down the array.

    public void moveQuestionUp(QuestionBase question) {
        int idx = questions.indexOf(question);
        if (idx > 0) {
            questions.remove(question);
            questions.add(idx - 1, question);
        }
    }

I think that the listview is being redrawn in HTML but the matrix of
data underlying it (that I retrieve here in the main page)

List<List<QuestionBase>> rows =
QuestionProcessor.getQuestionMatrix(templateWebModel.getEntity().getQuestions(),true);

does not get refreshed. I think I need to find a way to reload the
data for the listview, from within my panel on a page.

Cheers,
Pieter
