I have a page loaded from a button on a custom object to create an email. It renders the body and subject from an email template and displays the results for possible edit with a rich text field. I have two potential templates and I created radio buttons to select the appropriate template. If a different template is picked, I want to re-display the subject and body data for the selected template merged with the current data record. I coded everything to rerender the body section, but got the error cannot rerender a rich text object.

I was thinking a workaround would be to close the page and reload it. If the template is changed, the new template value is stored in the data record so it would be a simple matter to reload the page with the new template. My issue is that I cannot determine the correct method to close the current page from the controller and initiate the same page to reload on the same record. I've done quite a bit of VF recently, but some of the basic concepts still are not quite clear. Any help is appreciated.

  • You could try using javascript to reload the entire page, or put the visualforce page in an iframe and reload that. Would help to see a code sample on how your page is currently organized. – battery.cord Jun 6 '18 at 20:24
  • I added the controller and vf page code – Jerry Welliver Jun 6 '18 at 20:35

Theoretically you should just need a refresh no? Commit the template value to your record, refresh the page, requery the record, and render the template. Get rid of the re-render altogether and it should treat as synchronous operation and do a full refresh.

public PageReference toggleTemplate() {
    if (record.template1__c) {
        record.template1__c = false;
        record.template2__c = true;
    } else {
        record.template1__c = true;
        record.template2__c = false;

    //Setup reference to the page for redirect    
    PageReference newPage = new PageReference('/apex/Affiliate_Engagement?scontrolCaching=1&id=' + callersId);
    return newPage;

The page should do a refresh, you might need to return a null pagereference instead to trigger the refresh, can't remember or test right now.

  • That was my first thought, but I didn't know for sure how best to do it. I have been digging around and found redirect that seems to work. – Jerry Welliver Jun 6 '18 at 21:07
