Running into problems creating a subgrid similar to what you have in your multi subgrid example. I can create a normal subgrid but when I change opt["subGrid"] = true;
and opt["subgridurl"] = "myfile.php" the main grid shows but the subgrid shows nothing when I hit the expand button. It gives me an internal server error 500
Does the opt["subgridurl"] have to be the file name or could it be an object?
You can inspect using firebug it will show complete subgrid url with 500 error.
Now to debug, open that myfile.php page in a new tab by copying url from firebug and it will show error.
