This worked prior to UR 12.
Console error from developertoolkit reveals
"SCRIPT438: Object doesn't support property or method 'selectSingleNode' ".
Code snippet (error is on response.selectSingleNode - see below)
```
function executeWorkflow(entityId, workflowId, successCallback, errorCallback) {
var requestMain = ""
requestMain += " <request i:type=\"b:ExecuteWorkflowRequest\" xmlns:a=\"http://schemas.microsoft.com/xrm/2011/Contracts\" xmlns:b=\"http://schemas.microsoft.com/crm/2011/Contracts\">";
requestMain += " <a:Parameters xmlns:c=\"http://schemas.datacontract.org/2004/07/System.Collections.Generic\">";
requestMain += " <a:KeyValuePairOfstringanyType>";
requestMain += " <c:key>EntityId</c:key>";
requestMain += " <c:value i:type=\"d:guid\" xmlns:d=\"http://schemas.microsoft.com/2003/10/Serialization/\">" + entityId + "</c:value>";
requestMain += " </a:KeyValuePairOfstringanyType>";
requestMain += " <a:KeyValuePairOfstringanyType>";
requestMain += " <c:key>WorkflowId</c:key>";
requestMain += " <c:value i:type=\"d:guid\" xmlns:d=\"http://schemas.microsoft.com/2003/10/Serialization/\">" + workflowId + "</c:value>";
requestMain += " </a:KeyValuePairOfstringanyType>";
requestMain += " </a:Parameters>";
requestMain += " <a:RequestId i:nil=\"true\" />";
requestMain += " <a:RequestName>ExecuteWorkflow</a:RequestName>";
requestMain += " </request>";
// Execute it
var response = XrmServiceToolkit.Soap.Execute(requestMain, function (response) {
var workflowId = response.selectSingleNode('//a:KeyValuePairOfstringanyType[c:key=\'Id\']/c:value').nodeTypedValue;
successCallback(workflowId);
}, errorCallback);
}
