I built a real simple sample that downloads an object to the client, then sends the object back up to the server. I love how easy this is, but there's a problem with the upload:
Here's what comes down:
{"__serverType":"Westwind.AtlasTest.busCustomer","Name":"Rick","Company":"West Wind","Entered":new Date(2005,8,25,1,10,16)}
and here's what goes back up:
{"Customer":{"__serverType":"Westwind.AtlasTest.busCustomer","Name":"Rick","Company":"West Wind","Entered":{}}}
Notice the Entered date is no longer set isn't serialized properly - it's empty and on the server side a failure occurs.
This brings up another question: What hapens on an exception? Right now a 500 error and an HTML error page goes back. There's no trigger and no error nothing that happens on the client side page?
+++ Rick --More info...
The failure above doesn't seem to be related to the date field even - it looks like complex types do not marshall up at all. Even doing this on the client:
function btnSaveCustomer_Click()
{
var Customer =new Westwind.AtlasTest.busCustomer();
Customer.Name = document.getElementById("txtName").value;
Customer.Company ="West";
// Customer.Entered =new Date(2005,8,26,20,54,56);
alert(Customer.Entered);
Service = Westwind.AtlasTest.SimpleService.SaveCustomer(Customer,btnSaveCustomer_Click_Complete,btnSaveCustomer_Click_Complete);
returnfalse;
}
Fails. What goes up to the server looks right (I assume) and it's apparently picking up the type properly:
{"Customer":{"__serverType":"Westwind.AtlasTest.busCustomer","Name":"Rick","Company":"West"}}
Here's what I get back:

The Web Service is simple as can be for this:
[WebMethod]
publicbusCustomer GetCustomer()
{
//throw new SoapException("Failure dude!", SoapException.ServerFaultCode);
returnnewbusCustomer();
}
[WebMethod]
publicstring SaveCustomer(busCustomer Customer)
{
return Customer.Name;
}
Hi Rick,
I investigated this, and it is indeed a bug in the Atlas serialization code. In order for it to work correctly in its current form, you need to make sure that the fields you set into your client object (in your case Name and Company) have a matching public
property on the server object. Fields are not supported at this time, and maybe that's what you are using. If so, just switch to a property and you should be on your way. Thanks for reporting this issue, as it's definitely something we wnat to have fixed.
As for the fact that error reporting is lacking, it is one of those things that we didn't get to implement yet, but will be included in the next release.
Hope this helps,
David
