jQuery Grid Plugin - jqGrid

I actual got a problem with my jqGrid and I couldn't find any similar problem on the net.

Maybe I don't took the write tags for it, sorry tho.

Okay lets start talking about the real problem. I'm using inline editing, and I customized the

buttons a bit. I wanna use "ENTER" and "ESC"-Keys as shortcuts. This works fine. I'm manipulating the data in my grid local and only if the user is pressing a specialised button I'll

save the data in a file. This files are used to fill the grid too. So if the user now is editing any

row in the grid which isn't in my file yet, and he is canceling the editing by pressing

ESC, the complete row of data is getting deleted.

Anyone who can help me out?

Thanks in advice. Regards.

My grid:
