All I want to do is retrieve picklist options from a custom object and fetch the inputSelect element in a lighning controller. I am trying this way.. but I am getting an error.. If someone knows any other way to achieve this goal I will appreciate a lot..

I get the following error when trying to return a List of strings to fetch a inputSelect with retrieved salesforce custom object data: Uncaught Error in $A.getCallback() [Cannot read property 'set' of undefined]

This is my code:


  <ui:inputSelect  aura:id="InputDDSelectDynamic" class="slds-select"  change="{!c.onPicklistChange}"/>

CONTROLLER JS in doInit function:



    getOptionsPicklist: function(component, valor) {
    var action = component.get("c.getOptionsPicklist");
                "valor": valor

    var inputsel = component.find("InputDDSelectDynamic");
    var opts=[];
    action.setCallback(this, function(a) {
        for(var i=0;i< a.getReturnValue().length;i++){

            opts.push({"class": "optionClass", label: a.getReturnValue()[i], value: a.getReturnValue()[i]});

        inputsel.set("v.options", opts);




public static List<String> getOptionsPicklist(String valor){
    List<String> options = new List<String>();
    String valorSF;
    Schema.DescribeFieldResult fieldResult;

    if(valor.equals('DD')){ //  
        fieldResult = QuoteLineItem.SpaceDD__c.getDescribe();

    List<Schema.PicklistEntry> ple = fieldResult.getPicklistValues();
    for (Schema.PicklistEntry f: ple) {

    return options;

**** The inputsel returns "undefined".... I dont know why, its like I cant get the inputSelect element...

Thank you!!!


Problem solved.... I was calling to the apex controller in the doInit function but this inputselect was not visible when the component was open, so I call apex controller once this part is visible with aura:if

Sorry and thank you!!
