JQuery.ajax onerror function doesn't fire on the device

[dasaevc]

Hello guys,

I have an application that requires to make an Ajax synchronization on the server. I'm using the JQuery.ajax function which works well on success but yesterday my server was returning an error (basically a 500 Internal Server Error) and the device was not showing the error message. Here is the code:

jQuery.ajax({
            contentType: 'application/json',
            type: 'post',
            processData: false,
            dataType: 'json',
            url: DWWG.syncUrl + '/api/v1/jsonrpc.php',
            cache: false,
            data: $.toJSON({
				jsonrpc: '2.0',
				method: 'synchronize',
				params: [username, password, '[' + dataToSend.join(',') + ']', DWWG.preferences.purge, DWWG.preferences.fillWithLast],
				id: 1
			}),
            error: function(req,stat,err){
				alert('An Error has ocurred');
            },
            success: function(inp){
				// Success Code that works
            }
        });

Please, can you tell me why in the emulator (Aptana) the error message is displayed but not on a real device (N95) ?

what version of jquery are you using? the implementation of javascript is probably not quite the same between your device and your emulator.
i assume the success function was not called either?

I'm using the version 1.3.2 on the emulator and on the device. The success funcion is called when the response doesn't contain errors, but the error function isn't called when in the server a error happens.

i would suggest using the mobile version of jquery: http://jquerymobile.com/ which is supposed to be more compatible with mobile javascript engines

Thanks for your reply,

As fas as I know the jQuery mobile is an extension of the jQuery library not a modified version of it. Probably I'm doing something wrong, I'll review again my code and if i don't find something I'll try with this library.
