Dear Community, 

Couldn't find any posts that helped me, so I create a new one...

I'm trying to get item information from a list based on a lookup field. 

So I implemented a little javascript that's fired by a button.

function updateSupplierTemplate(){
var ctx = new SP.ClientContext.get_current();
var myList = ctx.get_web().get_lists().getByTitle('SupplierTemplates');
ctx.load(myList);
var templateID = NWF.RuntimeFunctions.parseLookup(NWF$("#" + supplierTemplate).val(), false);
var myItem = myList.getItemById(templateID);
ctx.load(myItem);
ctx.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
}
function onQuerySucceeded() {
alert('success');
alert(myItem);
NWF$("#" + supplierStreet).val(sStreet);
}
function onQueryFailed(sender, args) {
alert('Request failed.
Error: ' + args.get_message() + '
StackTrace: ' + args.get_stackTrace());
}

I could see with an alert box, that my lookupID variable is set fine. 

Also the SP.Context must be available because it returns an aobject] in an alert box.

The query goes in success function what I checked with an alert action. But as soon as I want to access myItem it returns "object not defined" in the developer function of the browser. 

Is this not a supported way to work with SP items inside a Nintex form?

Thanks for any help in advance.

What do you get on templateID ?

Try this code :

function updateSupplierTemplate(){
var ctx = new SP.ClientContext.get_current();
var myList = ctx.get_web().get_lists().getByTitle('SupplierTemplates');
ctx.load(myList);
var templateID = NWF.RuntimeFunctions.parseLookup(NWF$("#" + supplierTemplate).val(), false);
alert(templateID);
var myItem = myList.getItemById(templateID);
ctx.load(myItem);
alert(myItem);
ctx.executeQueryAsync(
function() {
alert('success');
alert(myItem);

NWF$("#" + supplierStreet).val(sStreet);
},
function(sender, args) {
alert('Request failed.
Error: ' + args.get_message() + '
StackTrace: ' + args.get_stackTrace());
}
);

}

Make use of REST query which gives you much clarity on what is going on and takes less lines. 

function GetTitle()
{
alert("method called");
var _siteUrl = _spPageContextInfo.webAbsoluteUrl;
var listname = "MyList";
var id = NWF.RuntimeFunctions.parseLookup(NWF$("#" + varParentItemID).val(), false);
NWF$.ajax({
url: _siteUrl + "/_api/web/lists/getbytitle('" + listname + "')/items(" + id + ")",
method: "GET",
headers: { "Accept": "application/json; odata=verbose" },
success: function (data) {
var _resultSet = data.d;
try {
NWF$("#" + varTitle).val(_resultSet.Title);
}
catch (e)
{
alert(e);
}

},
error: function (data) {
failure(data);
}
});
}

Dear Saud Kathri, 

thank you for your help, but it ended up in exactly the same way.
The REST way worked on first attempt - for what reason ever.

Best regards,

Rouven
