Local form editing demo and jqGrid 4.4.1
The main problem in the usage of my old demo from the old answer is in the line of code
this.processing = true;
jqGrid initializes now this to the DOM element of the table ($("#list")[0]) in calls of the most callback functions. So the above line have to be fixed to
options.processing = true;
There are other small changes which should be implemented also. The most important is the calling of $.unformat.date to decode of all fields used by the formatter "date".
The new demo used jqGrid 4.4.1 you can find here.
The full code you will find below

P.S. I don't tested the code with TreeGrid, but I hope it should work too. Probably one will need to make the same call of $.unformat.date on the columns with "date" formatter too.
