Greetings,


I'm trying to put a select dropdown on a SharePoint page to action a task. I want to use the Rest.svc since I don't have access to any server side code. Initially, I'm trying to get the list of actions to populate the select, but I'm getting "Access Denied" errors which I believe are stemming from the cross domain nature of this activity (SharePoint to the K2 server...)


Here's my function. What am I doing wrong? I've been trying to follow instructions from the following sites. http://www.k2underground.com/blogs/k2/archive/2012/05/10/integrating-k2-client-events-with-dynamics-crm-2011-using-k2-services.aspx and http://help.k2.com/en/k2u.aspx?DefaultFilters=%26Filter_Product%3D0010%26Filter_Channel%3D0100 and http://cyclops.nettrends.nl/blog/2011/04/k2-and-jquery-creating-a-simple-worklist/#more-342


function getActions(sn){
 var K2URL = K2Server + "/K2Services/REST.svc/Worklist/Items(" + sn + "/Actions?$format=json'";
 
 $.support.cors = true;
 $.ajax({
  url:K2URL,
  method: 'GET',
  contentType: "application/json; charset=utf-8",
  dataType: 'JSON',
  async: true,
  headers: {"X-Requested-With": "XMLHttpRequest"},
  crossDomain: true,
  error: function (data, error, status) {
   alert(status);
   alert(JSON.stringify(data));
  },
  success: function (data) {
   PopulateWorkflowDropDown(data);
  }
 });
}

So I'm partly figured out...


According to this page http://blogs.msdn.com/b/ieinternals/archive/2010/05/13/xdomainrequest-restrictions-limitations-and-workarounds.aspx #7 since I'm crossing from https on sharepoint to http on K2, I'm getting the access denied.


So I tried to access from http on sharepoint, but now the response is simply error, 500.


One other lingering question I have.. the web service for the Worklist needs to know who you are. IE passes the credentials when I go to the URL directly, but what is javascript passing? Does IE pass the NTLM authentication (intranet zone) as part of the javascript request?


Thanks.,


Doug

Well.. still in the http only world.. but typos have an impact ;-)


Here's my working function. I didn't close the ) around the serial number and there was a ' after json.


function getActions(sn){
 var K2URL = K2Server + "/K2Services/REST.svc/Worklist/Items(" + sn + ")/Actions?$format=json";
   
 $.support.cors = true;
 $.ajax({
  url:K2URL,
  method: 'GET',
  type:'json',
  async: true,
  crossDomain: true,
  error: function (data, error, status) {
   alert(status);
   alert(JSON.stringify(data));
  },
  success: function (data) {
   PopulateWorkflowDropDown(data);
  }
 });
} 


Now to go back to ssl...
