Thank you very much for this. Actually this is true. When we read the date we pass the rowObject as array - this from jsonReader configuration.

When we add or edit row we pass a object.

I've run into a minor problem with a custom formatter.  I'm basing the display value on the value of a different column.  When the grid iniitializes the rowObject passed to the custom formatter is an array.  However, when I return from a custom edit form and redisplay the row the rowObject passed to the same formatter with all the same settings (nothing changes in the colModel options) is now an object (as expected).

It's not a big deal.  I just look for the value I want either as an array element or a key name, however, I'm sending this on to you just in case it's important or you hear about this from someone else (or, of course, if I'm doing something wrong!).

Thank you again for all your help!
