    <p>We're using jQuery.ajax() methods to request server data on a number of pages on our MVC 3 web site. These requests are always marked with the 'POST' ajax parameter type and are typically invoked on page load or perhaps on a timer, that is to say, they are not a result of a user action (e.g. a mouse-click).</p> <p>When we look at the (Elmah) error log we see a number of entries as follows:</p> <blockquote> <p>A public action method 'GetMessageStats' was not found on controller 'Inbox.WebUI.Areas.Application.Controllers.StatusController'.</p> </blockquote> <p>The controller action is marked with the [HttpPost] e.g.</p> <pre><code>[HttpPost] public JsonResult GetMessageStats() { MessageStatsViewModel model = new MessageStatsViewModel { TotalNoMessages = MailDB.GetMessageCount(), MessagesInQueue = MailDB.GetQueueLength() }; return Json(model); } </code></pre> <p>and here is the invoking client script:</p> <pre><code>$(function() { var $totalMessages = $("#total-messages"), $queuedMessages = $("#queued-messages"); function getStats() { $.ajax({ type: "POST", url: "/Application/Status/GetMessageStats", dataType: "json", cache: false, success: function (data) { $totalMessages.text(data.TotalNoMessages); $queuedMessages.text(data.MessagesInQueue); setTimeout(function() { getStats(); }, 15000); }, error: function (xmlHttpRequest, errorMessage, exception) { throw errorMessage; } }); } getStats(); }); </code></pre> <p>On investigation it appears that some browsers (IE7/IE8, but maybe others) seem to issue a GET request in addition to the required POST request. It is noted that the user interface responds and behaves correctly under these browsers so the POST request is being serviced.</p> <p>Elmah is reporting the user agent as:</p> <p><strong>Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)</strong></p> <p>Has anyone else seen this problem? If so, have you found a way to avoid it?</p> <p>Thanks.</p>

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).
