I am working with the fetching of the fields form the data type. But after sometime during my work suddenly the data stops displaying on the screen. Returning to the datatype i found that all the data were vanished, but if tried to insert the older data as it is i am finding the error " Instance already existing ". Could anyone help me with this kind of error ?
