Adding items to a dropdown with jquery makes save form produce a correlation error

[#1]

Does anyone have any success with doing this?

My jquery looks

// remove the item not needed

NWF$('#' + choiceID).find("option[value='Test']").remove();

// add new item

NWF$('#' + choiceID).append($('<option value="' + managerUserprofile.email + '">' + managerUserprofile.firstName + '</option>'));

How can I populate a dropdown using items from javascript?

Hi Lars,

Looks like you are having the same issue as discussed here Re: Invalid postback and call back Argument : dropdownlist problem?

Maybe the discussion here might help you solve your problem

nintex forms javascript jquery dropdown

Content tagged with nintex forms javascript jquery dropdown

I have a drop down on the selection of this dropdown I am flitering the value from a sharepoint list and setting the another dropdown using the below code...

function Category_DropDown() {

var custDrpDwnVal = NWF$("#" + BusinessArea).val();
var context = new SP.ClientContext();
        var oList = context.get_web().get_lists().getByTitle('Categories List');
        var camlQuery = new SP.CamlQuery();    
  camlQuery.set_viewXml('<View><Query><Where><Eq><FieldRef Name=\'Title\'/><Value Type=\'Text\'>'+custDrpDwnVal+'</Value></Eq></Where></Query></View>');
        selectedListItems = oList.getItems(camlQuery);
  context.load(selectedListItems); 
  context.executeQueryAsync(Function.createDelegate(this, this.onSelectedListSuccessMethod), Function.createDelegate(this, this.onSelectedListFailureMethod));  

}

function onSelectedListSuccessMethod(sender, args)
{
var selectedListEnumerator = selectedListItems.getEnumerator();
var options = "";
var category = NWF$("#" + Category);
while (selectedListEnumerator.moveNext())
           {
     var oListItem = selectedListEnumerator.get_current();        
           var  categories = oListItem.get_item('Category_x0020_Value');
     options += "<option value='" + categories + "'>" + categories + "</option>";     
    }
       category.html(options);   
}

I get the value in my dropdpown but when i save these values i get a co relation id error and checked the logs and found below error :

Lars,

Did you ever solve your issue? I also have the same problem. Code works find populating dropdowns but get a correlation error when saving the form. The link Jeremy provided doesn't give any detail on how the problem was solved.

Hi Lars ,

Yesterday I could solve this problem.I dont think is there any logic in this solution.

I have put all the dropdown values in the Sharepoint dropdown Column as well which I am trying to set through Java.

I hope that solve ur issue.

I believe we can solve this issue by putting the control population inside Page_Preload but I'm not sure how to do this in Nintex Forms or with Javascript... Since my values are constantly changing at the source I can't manually populate the choice control with options beforehand. I need to be able to dynamically populate before and when the user makes a selection. Not sure if this is solvable with Nintex.
