Thanks for your answer. After a lot of search, I finally found out it was an EditAdapter that was wrongly witten. For the "adding(DataSet dataSet, ReadWriteRow row)" event, I did write the values on the DataSet. I changed the code to set values in the ReadWriteRow, and the problem was solved. This code was written monthes ago, and was working properly until some changes in the table structure. I don't know why it worked before, but now I have learned the lesson...
