    <p>I know there are a few questions out there but I've tried a lot of them and I'm still not able to even get my script to make it to the server. Here is what I currently have:</p> <p><strong>Javascript</strong></p> <pre><code>function UpdateSessionUser(user) { if (user != null) { var targetPage = "http://" + document.location.host + "/Sitefinity/Services/Sandbox/SessionUsers.asmx/UpdateSessionUser"; var dataText = { "jsonUser" : JSON.stringify(user) }; try { $.ajax({ type: "POST", url: targetPage, data: dataText, contentType: "application/json; charset=utf-8", dataType: "json", success: function (response) { alert(response.d); return true; }, failure: function (msg) { alert(msg); return false; } }); } catch (err) { alert(err); } } } </code></pre> <p><strong>Example of user object</strong></p> <pre><code>Object BaseID: "fe85149c-71f2-4c61-b7c6-a00300e2f84e" HasChanged: true IsReferralReceived: false IsReferralRequired: true IsSeatApproved: true Name: "Miles" ReferralFromUser: null ReferralFromUserID: null ReferralReceivedBy: null ReferralReceivedByUserID: null ReferralReceivedOn: "/Date(-62135578800000)/" RegisteredOn: "1330281960000" SeatApprovedBy: null SeatApprovedByUserID: null SeatApprovedOn: "/Date(-62135578800000)/" SeatNumber: "2" SessionID: "d0773d5e-aeeb-4b9c-b606-0a564d6c5845" UserID: "6af2fd9e-b4b6-4f5a-8e9c-fe7ec154d4e5" __type: "SandboxClassRegistration.SessionUserField.ClientSessionUser" </code></pre> <p><strong>C#</strong></p> <pre><code>[WebMethod] public bool UpdateSessionUser(object jsonUser) { return SessionUserHelper.UpdateSessionUser(new ClientSessionUser(jsonUser)); } </code></pre> <p>Why does my JSON call never make it to the server? I've put a break point at the very beginning of the function (before the return) just so I can look at the jsonUser object parameter but it never makes it there.</p> <p>All I get in return is this error:</p> <p><em><strong>POST <a href="http://localhost:60877/Sitefinity/Services/Sandbox/SessionUsers.asmx/UpdateSessionUser" rel="nofollow">http://localhost:60877/Sitefinity/Services/Sandbox/SessionUsers.asmx/UpdateSessionUser</a> 500 (Internal Server Error)</em></strong></p> <p>--- UPDATE</p> <p>Here is the final result (I had to "stringify" the object and then the final dataText being sent). The webservice method was unchanged</p> <pre><code>function CallWebServiceToUpdateSessionUser(target, user) { var dataText = { "jsonUser": JSON.stringify(user) }; $.ajax({ type: "POST", url: target, data: JSON.stringify(dataText), contentType: "application/json; charset=utf-8", dataType: "json", success: function (response) { alert(response.d); return true; }, failure: function (msg) { alert(msg); return false; } }); } </code></pre>

    1. CO500 is a server error. Your call _did_ reach the server. Look in the Application event log to see if there's an ASP.NET warning showing you the exception that occurred.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
