When following the official steps to create a Lightning app and Lightning components from a Visualforce page, components ui:inputNumber, ui:outputNumber and others related to displaying numbers don't work properly. This happens in all browsers and in the Salesforce1 app. The most detailed error message I get is "undefined is not an object (evaluating 'this.$symbols$["zeroDigit"].charCodeAt')"

When running my components from a straight Lightning app, $Locale is initialized and everything works fine.

Here is a minimal code example to show the problem Visualforce page, SimpleTestPage.page:

<apex:page showHeader="false" docType="html-5.0">
<apex:includeScript value="/lightning/lightning.out.js" />

<div id="lightning" />

$Lightning.use("c:SimpleTestApp", function() {
{ "simpleNumber": 10 },
function(cmp) {
// do some stuff

Lightning app, SimpleTestApp.app:

<aura:application access="GLOBAL" extends="ltng:outApp">
<aura:dependency resource="c:SimpleTestCmp" />

Lightning component, SimpleTestCmp.cmp:
<aura:component >
<aura:attribute name="simpleNumber" type="Decimal" default="100"/>

<!-- ui:inputNumber displays but shows this error. -->
<!-- afterRender threw an error in 'markup://ui:inputNumber' : Cannot read property 'charCodeAt' of undefined -->
<ui:inputNumber label="Simple" value="{!v.simpleNumber}" />

<!-- ui:outputNumber doesn't display at all, shows this error. -->
<!-- Uncaught error in $A.run() : Cannot read property 'charCodeAt' of undefined -->
<!-- ui:outputNumber value="{!v.simpleNumber}" / -->

This issue has been fixed with the latest patch to Winter'16 and as of this morning all instances should have the fix in place.

  • would be a great help if you can post the workaround

    The workaround introduces an extra server trip and I am concerned that once I put it out there its going to stick and eventually come back as a new case about performance. Nov 4, 2015 at 23:38
  • @dough lol do what you feel is right :). I don't have any need only curious to know the fix
