Since a sandbox has been upgraded to Summer 18, I've been having a problem with a lightning:textarea showing undefined within it's box but only when I have used an apex controller to return the sobject fields.

Here is an example component in a Summer 18 org.

Rendered Component

And this is how it renders in a Spring 18 org.

enter image description here

I should note that all components are v42 in both orgs, not v43.

Here's an example Component:

<aura:component controller="TestLightningTextarea" implements="flexipage:availableForAllPageTypes,forceCommunity:availableForAllPageTypes,force:hasRecordId">
  <aura:attribute type="Contact" name="contRecord" access="private"  />
  <aura:handler name="init" value="{!this}" action="{!c.doInit}"/>
  <lightning:textarea label="Textarea" value="{!v.contRecord.Description}" />
  <lightning:input label="Input" value="{!v.contRecord.Description}" />

Component Controller:

doInit : function(component, event, helper) {
  var getContactAct = component.get('c.getContact');
  getContactAct.setParams({'contactId' : component.get('v.recordId')});
  getContactAct.setCallback(this, function(response){
    component.set('v.contRecord', response.getReturnValue());
  }, 'SUCCESS');

Apex Controller:

public with sharing class TestLightningTextarea {

  public static Contact getContact(Id contactId) {
    return [SELECT Id, Description FROM Contact WHERE Id = :contactId];


Console Log of the returned Contact record

The controller queries the field, but it's not included in the payload to the lightning controller because it's empty.

Has anyone else seen this, and is there a way I can report this to Salesforce easily, given the customer I'm working with doesn't have Premier Support (thus no development support)?

    Do you work for a Partner? If you could mock this up in a pre-release org with the same results, you could report it with a case in the Partner Community. You could also try finding an appropriate group in the Success or Partner community that would tag someone appropriately technical on the Lightning team.

  • I've replicated it in a prerelease org, so i'll try the partner portal support route. Thanks Commented May 10, 2018 at 19:35

This appears to have been fixed with a recent Summer 18 patch, no mention of it anywhere though.
