So here is the method that returns the selectItem list. Each time it
creates a new array. Do you still think this might be the issue? I am
really lost on this one:
public SelectItem[] getCurrentQuestionAnswers()
{
Question currentQuestion = this.questionList.get(questionCount);
int qWeight = currentQuestion.getQuestionWeight();
SelectItem[] answers = new SelectItem[5];
answers[0] = new SelectItem(Integer.toString(qWeight) , "SA");
answers[1] = new SelectItem(Integer.toString(qWeight - (qWeight /
5)) , "A");
answers[2] = new SelectItem(Integer.toString(qWeight - ((qWeight /
5) * 2)), "N");
answers[3] = new SelectItem(Integer.toString(qWeight - ((qWeight /
5) * 3)) , "D");
answers[4] = new SelectItem(Integer.toString(qWeight - ((qWeight /
5) * 4)) , "SD");
this.questionCount++;
return answers;
}
This method does declare a new array each time
