On IE 8, when calling trigger('reloadGrid') on jqGrid object, the grid looks like been loaded and its also been emptying.
my code:
$('#myList').setGridParam({page:1});
$('#myList').setGridParam(url: 'http://..');
$('#myList').trigger('reloadGrid');
In Chrome the request is sent to the server and the data is been refreshed appropriately.
EDIT: The request is sent to the server
After re-inspecting the request, the request did reach the server but its URL parameter was in Unicode character(U+05D0-א-Hebrew Letter Alef).
IE does not automatically encoding the URL in contrary to Chrome browser.
