AI302.Containers bug



I'm using AI302.Containers, version 20040727. This call to Sorted_Sets.Element raises a CE:

      Cur := Node_Keys.Find (Nodes, Node);
      if Cur /= Null_Cursor then
         Old_Lev := Element (Cur).Level; -- <== HERE

But the set Nodes is empty yet. So Find should have returned a Null_Cursor, no? And the call never made. Node_Keys is an instance of Sorted_Sets.Generic_Keys. Thanks.
