Web Service and Custom Type(Enumeration)

Hello,

I have a web service with a method called "Login" Login returns a custom enumeration type called "MethodStatus". I am trying to call this method in Atlas, my client code is below

 function OnbuttonGo_click() { //Call script proxy passing the input element data var object = Crisp.ParentWebService.MainService.Login( 'd','d', //params OnComplete, //Complete event OnTimeout //Timeout event ); return false; } function OnComplete(result) { alert(result); } function OnTimeout(result) { alert("Timed out"); }

This method works fine if I change the type in my Login status to String but when I use my enumeration it fails
giving me the following error message:

Key cannot be null.

Parameter name: key

Server Error in '/AtlasWebSite1' Application.
Key cannot be null.
Parameter name: key

You're doing something else wrong somewhere, and I don't know from your code what it is. I just did the part that you think is tripping you up, and it works fine. Code follows:

<... Html stuff that builds a pair of text boxes and a button ...>

<script type="text/javascript">

function button_Click()

{

var name = document.getElementById("userName");

var pass = document.getElementById("passWord");

requestService = TestEnums.MyService.Login(

name.value, pass.value

OnComplete,

OnTimeOut);

return false;

}

function OnComplete(result)

{

alert(result);

}

function OnTimeOut(result)

{

alert('timed out');

}

</script>

<... closing html stuff ...>

now the web service

<... web service header, using statements, and so on ...>

[WebMethod]

public Status Login(string a, string b)

{

if(a==b)

return Status.Authenticated;

else

return Status.Anonymous;

}

<.... Enum ...>

publuic enum Status

{

Anonymous,

Authenticated

}

Now, what happens is that the thing runs, and it alerts 0 or 1. I suspect you'd have to handle the enum in javascript as well in order to translate the enumeration into something meaningful on the client. But the bottom line is that passing a custom type is not error-generating action.

Hello,

I have fixed the problem now the problem was because I never set a namespace for the enumeration. I had set a namespace for my service and not for my enumeration.

Thank's alot for your help!

No problem, glad you found it!
