  It happens when you use the SetColumnValue("ColumnName", val)  to set object properties, setting a value to column that does not exists in the table schema. Also, maybe you forget to populate the Table schema of the class.

  
  

  I'm sorry because i'm too late, but I needed help with this and have to find this solution by myself.
