I think that nothing should be done. For me all work correct. If the value is not found the empty string is returned.

Also please check your editoptins values - maybe you end it with ";" at end which is not correct  - i.e "1:one;2:two;" - this string is not correct which caouse to return undefined.

I found that when you set a column's formatter property to “select” and recieve a NULL value from the server, it displays “undefined“. There should be an option to set what to display in those cases, because in my case, what I want it to display is just an empty string.

By the way, I can't set an option like this (which I use to set a NULL value) if I try to pass the “editoptions”:”value” parameter like an object:

I think the drop-down list should automatically display an empty option as above when the “editrules”:”required” option is false.

---EDIT---

I thought another possibility. Maybe adding an afterFormat event, which fires after aplying the formatter to the grid. This way I can change whatever I don't like.

Thanks, see you
