Can any one help me on this....
In classic  while passing object record id in the URL will get the field values on the page ,how can we achieve this in the lightning.
Here am tryng same but unable to get field values and where can I pass the id in the lightning,below is my component and app.

<aura:component implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes" access="global" >
    <aura:attribute name="expense" type="expense__c"/>
<p>Amount:<ui:outputCurrency Value="{!v.expense.Amount__c}"/></p>
<p>Client:<ui:outputtext value="{!v.expense.Client__c}"/> </p>
<p>Date:<ui:outputdate value="{!v.expense.Date__c}"/></p>
<p>Reimbursed?: <ui:outputcheckbox value="{!v.expense.Reimbursed__c}"/></p>
    <ui:outputText class="form-control" aura:id="recid" value="{!v.recordId}" />

<aura:application >

Thanks in advance.

I am basically diving into Lightning Component Development as I generally learn faster applying examples to real-world problems. In this case, I am trying to replace a javascript button that launched a window with a Visualforce page that has its own styling, Unfortunately adding the launch as a quickAction will open the window, but I can't get the size to match the content, making it largely unusable, even with scroll bars. 

Instead, I figure since Lightning Components are so Javascript heavy anyway, why can't I just build a Lightning Component featuring a UI button, an APEX controller providing a method to return the record ID, and a js controller with a doInit()function that queries the record data, while the button click launches the newInterview() method which contains the original Javascript that opens the Visualforce page using the parameters from the current record. That's the idea anyway...

Here is how I tried to build it:

<aura:component controller="AuraMethods" implements="flexipage:availableForAllPageTypes,force:lightningQuickAction,force:hasRecordId" access="global" >
	<aura:attribute name="opp" type="Opportunity"/>
    <aura:handler name="init" value="{!this}" action="{!c.doInit}" />
    <ui:button label="New Interview" press="{!c.newInterview}"/>

	doInit : function(component, event) {
		var action = component.get(c.findOppById("v.recordId"));
        action.setCallback(this, function(a) {
            component.set("v.opp", a.getReturnValue());

    newInterview : function(component, event){
        if(component.get("v.opp.School_Interview_Type__c")== '3W' || component.get("v.opp.School_Interview_Type__c") == '3W+School'){ 
        	window.location.href = "/apex/AM_Time_Slots2?id="+component.get("v.opp.Id")+"&Name="+component.get("v.opp.Name"); 
        	alert('please do not make an appointment AM time when the School Interview Type not equals 3W,only need to confirm the following AM given in the school time.'); 

public with sharing class AuraMethods {
    public static Opportunity findOppByID(String OppId){
        return [Select id, Name, School_Interview_Type__c from Opportunity where Id = :OppId];

That's pretty much it. The Component appears in the Custom Components section of my Lightning Page Layout for the Opportunity in the App Builder, but when I try to place it I get the following error:

'Action failed: c:InterviewScheduling$controller$doInit [c is not defined] doInit()@components/c/InterviewScheduling.js:10:30'

I know I'm still a bit green to JS, as well so I may have missed something. More important, I've seen several posts about the difficulty of getting a javascript button's functionality to work in Lightning. I really just want to be able to launch this Visualforce page from within the Opportunity and have it appear in all its glory rather than in some dinky popup window where I can't adjust the width in the settings. 

I appreciate all responses. Kindness and patience is appreciated. I will learn this. 




I need to know the opener of a lightning application. for this, I would use window.opener. The value of window.opener is not managed by javascript (execution of code stops) when the current window have been opened by another one.

What is the reason why this regular environment variable is not useable in ligthning ?

Hello. I am more of an admin than a developer. Anyway I'm working on a community, and trying to figure out how to customize the apex controller that is automatically created for the Self Registration lightning component that is also created when communities are activated. This class is called LightningSelfRegisterController and it's code is included.

All, I want to do is put some system.debugs into the code so that I can get an understanding of how a portion of it is working. So, putting the debug statements in is no problem. The problem is that I now expect a log to be generated when I use the Self-Registration page, but no logs are generated. I suppose this is because the code is not executed in the context of any user that I have a trace flag on. So, I tried putting a trace flag on the class itself, but that hasn't worked either. 

Can anybody point me in the righ direction?

According to this^ thread it isnt possible to sort activity feed... pretty much at all.

This seems insane to me, but before I try to hunt down a solution I wanted to see if anyone here has experience (or a solution!) to share.

Keep getting this error below in the App Manager panel and have been seeing werid behavior in other places.  Some apps I did for trailheads no longer function correctly either, some produce Aura.loadComponent(): Failed to initialize application errors while others are not displaying any data.

Hi - I have a lightning component that is working on Desktop with lightning experience. The same component is not working on Mobile browser  (Salesforce1).

Here is the error.

No idea what the problem is. Thanks, JD
I am implementing lightning:tabset and lightning:tab to display tabs in a lightning component -- I am trying to conditionally display one particular tab based on a value returned by the controller -- but it is not rendering the tab. Does anyone have any insight into how to achieve this functionality? Also, when I try to set the selectedTabId in the init function, I get an error saying the tab does not exist.

	doInit : function(component, event, helper) {
        var action = component.get("c.getSearchFromId");
            "recordId": component.get("v.recordId")
        action.setCallback(this, function(response) {
            var state = response.getState();
            if(state === "SUCCESS"){
                if(response.getReturnValue().Candidates_Visible__c == true){
                } else {

But when i try calling it from Vf page its not able to take the div id and reads it null and hence shows below error , can anybody help me on this,thanks..

This page has an error. You might just need to refresh it. Error in $A.getCallback() [Cannot read property 'appendChild' of null] Callback failed: apex://PMD_DispRecordsController/ACTION$getRecords Failing descriptor: {markup://c:PMD_LightningHomepage}

Please suggest .

Note : This coponnent Works fine when i do not call it from Vf page i.e preview it directly.

Hi All,

Is it Safe to use document.getElementById(id) in Lightning Controller.

In recent release they mentioned that we cannot modify DOM objects .

Like using 

Etc Etc.???


Getting the error "A.getCallback(): 'callback' must be a valid Function : false" while running my component. when such error occurs ?
How does map type of attribute work? How can I receive the list of keys and list of values from the map in JavaScript?

I receive data from apex method, and I would like to use aura:attribute with map type to keep Id and Quantity, Is it possible to keep it on the client side using map type of attribute?
<aura:attribute name="OpportunityLineItem" type="Map" default="{ '0065800000CINW0': 'name1', '0065800000CINWP': 'name2' }" />
