I have a visualforce page having a Case detail view from which there is a link which opens a new visualforce Page for attachment for that particular case. I am opening that attachment visualforce page by passing the values through Query string.

<apex:outputLink styleClass="btn btn-link" target="_top"
                value="/WSC_NewAttachment_Case?varCaseId={!Case.Id}&varUpload=1">
  New Attachment 
</apex:outputLink>

Then there is a the visualforce Page and controller.

The problem is that even through the attachment is working fine, I am not able to redirect the user back to the Case Detail page from which the user clicked the New Attachment link (button). After attachment the user stays on the same attachment visualforce page. User should be redirected back to Case Detail on Finish Uploading & Submit with No attachment (or Cancel) button. Please tell me the best way to redirect user back to their selected CaseDetail page preferablly using visualforce or Apex as well (if Needed).

// The visualforce Page:

<apex:page controller="WSC_NewAttachment_Case" docType="html-5.0" showHeader="false" sidebar="false" cache="false" standardStylesheets="true">

                <!-- Insert global site header css and meta tags-->
   <c:AWSHeader />
      <style type="text/css">
             #main-content{
             margin-left: 0px;
             }
       </style>

</head>
      <body>
          <!-- container section start -->
           <section id="container" class="">

  • in your upload method change last 'return null;' to 'return new PageReference('/'+varCaseId);' – Ilya Lepesh Jul 9 '16 at 21:32

The most proper way to construct a redirect PageReference is to use the StandardController.view method. In this case, you need to also construct the record itself with the varCaseId.

PageReference view = new ApexPages.StandardController(new Case(Id=varCaseId)).view();
return view;

You don't even need to cache it, I just do so here because I find it more illustrative. As @Ilya mentions in the comments, you want to replace return null with this at the end of your upload method.

For custom Visualforce Pages, the programmatic approach would be:

PageReference detail = Page.CaseDetail;
detail.getParameters().put('id', varCaseId);
return detail;
  • Thanks a lot Adrian. You gave me an idea of how to go forward about it. I was trying to redirect it in the wrong part of the code earlier. Also the specific requirement was that I cannot use the standard controller pages as it is for a community and use has to be redirected back to specific CaseDetail visualforce page with the same ID. Here is how I resolved it with the help of your idea. PageReference view = new PageReference('/apex/CaseDetail?id='+this.varCaseId); return view; – AMAN Jul 10 '16 at 22:44
  • @AMAN See my updated post for a cleaner approach to that as well. – Adrian Larson Jul 10 '16 at 23:01
