Hello Deepika,
collection wrapper->get_current will always give me first entry. Even though i am having my table in Editable mode, if i change the first entry then all the entries in that column will be Changed 
. What should i do now ? Saving and other things are happening fine :-). now only problem in setting the column field.
Thanks and Regards,
Kaushik M
