Problem in saving the data in NWDS

Hi All,

I am new to Web Dynpro. I am developing a Web Dynpro project in NWDS. Now if I am manually editing a java code & saving it, all the lines which I have added gets deleted . That means no change is getting updated.

Can anyone please help me regarding this. Is there any settings to be made in NWDS for this ?

Thanks & Regards
