+Summary: ListBox - Multi Selection bug (A fix is provided)
+Please fill in this template when reporting a bug, unless you know what 
+you are doing.
+Description of Problem:
+Items are not selected when the ListBox is at MultiSelection mode.
+Steps to reproduce the problem:
+1. Open the attached aspx file.
+2. Click on the "Bind" Button.
+3. Select some items
+Actual Results:
+None of the items is selected
+Expected Results:
+The selected items should be selected
+How often does this happen? 
+Additional Information:
+The bug source is the line:
+if(!updated) Select(final);
+that should be:
+if(updated) Select(final);
+But I made additional optimizations to the algorithm so I highly suggest
+to insert my whole implementation for the method.
