Error when working with Agentry Complex table

Hello Gurus,

I follow the tutorial Flight Booking and try to load a complete table onto my Agentry client. However, when I transmit from Agentry server, it display the error in the log:

Exception: 11:20:06 07/24/2014 : 20 (Agentry3), JavaBackEndError (java.lang.NoSuchMethodException: com.syclo.sap.mm.object.VendorCT.<init>(com.syclo.agentry.ComplexTableSession, java.util.GregorianCalendar)),

VendorCT is the complex table.

Please help me. Thank  you.
