Update requires a valid UpdateCommand when passed DataRow collection with modified rows.

Question

It is my
understanding that when using a TableAdapter and selecting the proper
options, Insert, Delete and Update statements are generated. The
Update statement should work just using the following:
myTableAdapter.Update(changes);
Where changes is the DataSet containing the modified data.
This logic works great for one of the tables in the DB but not for another.
Learning this new stuff is Confusing at best - Frustrating at worst.
Help appreciated,
Michael

ISiM to organize COMAD 2009 - the 15th International Conference - Call for papers
Dear All,
The 15th COMAD is organized by the International School of Information Management (ISiM), University of Mysore during December 9-11, 2009 at Infosys Technologies campus, Mysore. Similar to previous years, COMAD   2009’s scope  will  include  all   areas  in  the  data  management  space  including database management  systems, Web and Information  Retrieval and Data Mining. For details:  http://www.isim.ac.in/comad2009
For close to two decades COMAD – the International Conference on Management of Data, modeled along the lines of ACM SIGMOD, has been a premier international database conference hosted in India. The first COMAD was held in 1989, and it has been held on a nearly annual basis since then. COMAD always had significant international participation with about 30% of the papers from outside India including Europe, USA, and East/South East Asia.
Call for Papers  
Original  research  submissions are  invited  not  only  in  traditional database areas  but also  in Data Quality, Web,  Information  Retrieval and Data Mining.
We invite submission of original research   contributions as well as proposals   for demonstrations, tutorials,   industrial presentations, and panels.
Areas of interest include but are not limited to:
Data Management Systems:
   * Benchmarking and performance evaluation
   * Data exchange and integration
   * Database monitoring and tuning
