I'm trying to call an Apex Controller method from JS Helper of the Lightning component. But when I try to pass a parameter of the type of a custom object the apex method is not getting invoked.

I don't understand what is causing this error, no error is shown on Debug Log. There are no namespaces used in the org.

Kindly help me out.

I have shared the code fragment.

Lightning Component

<aura:component implements="forceCommunity:availableForAllPageTypes" access="global" controller="MSIApplicationFormLightningController">

  <aura:attribute name="application" type="Applications__c" />

  <div aura:id="page-content" class="toggle">

      <ui:inputText value="{!v.application.Major__c}"
                    class="slds-input question-input" 
                    required="true" />      

       <div class="button-grid">
           <ui:button class="custom-button" label="SAVE DRAFT" press="{!c.saveApplicationAsDraft}"/>



JS Controller

    saveApplicationAsDraft: function(component, event, helper){

            helper.saveApplication(component, event);



JS Helper

    saveApplication: function(component, event){  

        var action = component.get("c.saveMSIApplication");

        action.setParams({ "application" : component.get("v.application")});

        action.setCallback(this, function(response){          



            if(component.isValid() && response.getState() == "SUCCESS"){





APEX Controller

public without sharing class MSIApplicationFormLightningController {

    public static String saveMSIApplication(Applications__c application){

      String appId = 'test';

      return appId; 

}//End of class

Console log:

 "ERROR" for response.getState() 
 "null" for response.getReturnValue()

    Try logging response.getError() and see what it tells you – Fernando Gavinho Oct 20 '16 at 15:25
  • How are you supplying application to your component? It's not set on init nor is a default value declared. – André Dion Oct 20 '16 at 16:27
  • Thanks a lot for everybody, after specifying the default attribute value the Apex Controller method got invoked. – Ram Oct 21 '16 at 5:17

Always declare a default value for your attribute so that it is not undefined

<aura:attribute name="application" type="Applications__c"  default="{ 'sobjectType': 'Applications__c',
