title: DevExpress Scheduler is not filled with data from SQL Server database
body: <p>I want to fill XtraScheduler with data from database stored procedure. The scheduler is filled only with one record and I cant understand why. The stored procedure is correct and returns 8 records.</p>
  
  <p>Here's my stored procedure:</p>
  
  <pre><code>ALTER PROCEDURE [dbo].[Reservations]
  AS
  BEGIN
      SELECT  
          HallSeat.HallGroupID, Color, Price, SeatRow, SeatRowLetter, 
          SeatNumber, SeatNumberLetter, ReservationTime, IsReserved 
      FROM 
          HallSeat
      LEFT JOIN 
          HallGroup ON HallGroup.HallGroupID = HallSeat.HallGroupID
      LEFT JOIN 
          Hall ON HallGroup.HallID = Hall.HallID  
      WHERE 
          (IsReserved = 'true') 
  END
  </code></pre>
  
  <p>I assigned <em>Appointments Data Source</em> in Scheduler to reservationsBindingSource which represents my stored procedure, and I chose the mappings like this:</p>

  <p>In the code I fill reservationDataAdapter like this (it was created automatically):</p>
  
  <pre><code>this.reservationsTableAdapter.Fill(this.filharmonijaDataSet1.Reservations);
  </code></pre>
  
  <p>Somehow the scheduler always shows only one record, even though there's a lot more... Where is the problem?.. </p>
