I'm currently making a custom editor in Visualforce that adds things to a related list. Things from this list are selected and then when the "add packages" button is click it should make the records, and redirect the page back to the Opportunity the user was in.

What happens is that it stays on the Visualforce page, but adds the records. No errors are displayed on the page but here are the errors I receive within the developer console:

Select_Package?retURL=%2F006L0000006EKr1&CF00NL0000003UiUg_lkid=006L0000006EKr1&sfdc.override=1&CF0…:1 
Refused to display 'https://cs8.salesforce.com/006L0000006EKr1' in a frame because it set 'X-
Frame-Options' to 'SAMEORIGIN'.

VFDevMode.js:21 Uncaught SecurityError: Sandbox access violation: Blocked a frame at 
"https://c.cs8.visual.force.com" from accessing a frame at 
"https://c.cs8.visual.force.com".  The frame being accessed is sandboxed and lacks the 
"allow-same-origin" flag.

I'm not sure what could be causing this, or how to fix it, so I will post the full visualforce and extension code.

Visualforce:

<apex:page standardController="Opportunity_Package__c" extensions="MetadataPackageEditor" sidebar="false" showHeader="false">
  <apex:outputPanel id="all">
  <apex:outputText >{!NOW()}</apex:outputText>

  <apex:form >

      <apex:outputField value="{!Opportunity_Package__c.Opp_Package_Rel__c}"/>

      <apex:pageBlock title="Select Package(s)">
      <apex:pageMessages />

          <apex:pageBlockTable value="{!packages}" var="o" id="table">

Is is possible that you are embedding this VF page in a standard page layout? That may be why you are getting the cross browser error. If you are, consider launching the page from a custom button on the source record, then redirecting back to the record when the Save completes. You shouldn't have to put the full URL into your pagereference, something like this should work fine:

pagereference pg = new pagereference('/'+oppid);
pg.setRedirect(true);
return pg;

  • This page is being redirected from the new button, from a related list. This page is not accessible anywhere else than from this related list, through the new button. And I've already tried that method and it provides the same error. – Cody Beaner Mar 5 '15 at 21:23
  • Are you using Chrome? It could be because of the development footer, and Chrome interacting poorly. If you are using Chrome, try a different browser, and try it with the development footer turned off. – JimRae Mar 5 '15 at 21:34
  • How would I turn the development footer off? – Cody Beaner Mar 5 '15 at 21:35
  • From your user record, uncheck the Development Mode checkbox. Or, your can modify your url to include the core.apexpages.devmode.url=1 parameter – JimRae Mar 5 '15 at 21:47

Two things i would request you to do.

1) Remove the hardcoded instance URL and use a relative URL

PageReference pRef = new PageReference('https://cs8.salesforce.com/'+oppId); Change to PageReference pRef = new PageReference('/'+oppId);

2) In case the above doesnt work, remove redirect and return Page reference directly using the relative path.

  • I had already tried that before with the same results – Cody Beaner Mar 5 '15 at 21:10
  • when I hover over the button in the left corner of your screen it will display the url path. if it is displaying visualforce. Then change the path in your pagereference to '../'+oppId – Suresh Mar 5 '15 at 21:15
