Hi every one 
For approve or reject tasks from board page I use this function:
function updateFlexiTaskProcess(TaskID, Outcome, Comment, color) {
var SiteUrl = _spPageContextInfo.webAbsoluteUrl;
var WS_Url = "/_vti_bin/nintexworkflow/workflow.asmx";
var FullURL = SiteUrl + WS_Url;
var CallStatus = "";
//create soap envelope
var soapMessage = '<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:m="http://nintex.com">
<soap:Header>
</soap:Header>
<soap:Body>
<m:ProcessFlexiTaskResponse2 xmlns="http://nintex.com">
<m:comments>' + Comment + '</m:comments>
<m:outcome>' + Outcome + '</m:outcome>
<m:spTaskId>'+ TaskID + '</m:spTaskId>
<m:taskListName>Workflow Tasks</m:taskListName>
</m:ProcessFlexiTaskResponse2>
</soap:Body>
</soap:Envelope>'
var AjaxDefered = $.ajax({
url: FullURL,
type: "Post",
dataType: "xml",
data: soapMessage,
cache: false,
contentType: "text/xml;charset=utf-8",
success: function () {
CallStatus = "Task has been processed successfully";
...
//color the button and change text
$('.' + className + ' a[id=' + TaskID + ']').parent().parent().css('color', color).text(text).prepend(icon);
console.log(CallStatus);
},
error: function (data) {
CallStatus = "failed" + data;
}
});
}
It goes always to success - but the task is not updated...
What could be the problem?
