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
