Hi Jill,

I hope you had a good holiday.  I have tested this issue on both IE8 and Firefox 3.0.11.  When I click my button as a user with development turned on, everything works as I expect.  When I click my button as a user with development turned off, I see the page within a page.  My objective here is to have the entire page refreshed after I perform the action.

I have created a simple Visualforce page and controller extension based on the Account object.  With this simple test I experience the same issue.

Here is the controller extension.

public with sharing class TestControllerExtension {

private ApexPages.StandardController stdController = null;

private Account acct = null;

public TestControllerExtension(ApexPages.StandardController controller) {

this.stdController = controller;

acct = (Account)stdController.getRecord();

}

public PageReference test() {

PageReference pageRef = null;

String refId = acct.id;

pageRef = new PageReference('/'+refId.subString(0,15));

pageRef.setRedirect(true); return pageRef;

}

}

...and here is my test Visualforce page.

<apex:page standardController="Account" extensions="TestControllerExtension">

<apex:pageBlock >

<apex:messages >

</apex:messages>

<apex:actionRegion >

<apex:form id="theform" >

<apex:commandButton action="{!test}" value="Test" />

</apex:form>

</apex:actionRegion>

</apex:pageBlock>

</apex:page>

On the account layout, I insert a new section and then I put this Visualforce page in that section.  The section is defined as a single column.  When I open an account I see the Test button in the new section.  Clicking the Test button displays the behavior I have described above.

I don't know if this is a feature that isn't supported, or I am trying to refresh the whole page in the wrong manner or this is a bug.  BTW, I also see this behavior (page within the page) if an exception is thrown in the extension.

Please let me know if you think I should submit a case for this.

Thanks for your help.
