<!-- bug on 45493. Right now, I am getting an error other than the one on the bug. the original issue was:
To reproduce the bug:
1. in xsp, start the following aspx page.
2. Select an exam, e.g. "calculus".
3. Click "view subscriptions". The list of subscription correctly
appears.
4. Now click "view subscriptions" again, _without_ changing the
selection (i.e. leave "calculus" selected). An error message appears,
complaining that there was no exam selected. But it was!
-->
<%@ language="C#" %>
<script runat="server" >
void Page_Load(Object Source, EventArgs E) {
if (!IsPostBack){
#region fill the listbox exams
exams.Items.Clear();
exams.Items.Add(new ListItem( "math"));
exams.Items.Add(new ListItem( "calculus"));
exams.Items.Add(new ListItem( "english"));
message_subscriptions.Visible=false;
subscriptions.Visible=false;
