Rerendering the detail object only refreshes the related list

When I can for my form, which holds my detail object, to be rerended only the related list gets rerendered, but the field that I updated does not refresh with the new value.  If I press F5 to refresh the page it appears.  This field needs to be populated before my related list can populate, so we know that the underlying field is updated it just does not appear.  Here is my code.  Thank you for your time.

<apex:page standardController="Opportunity" extensions="workFlowData"  >
        <apex:form id="oppsPage"  rendered="{!renderMe}">

I suggest wrapping what you need to rerender in an <apex:outputPanel id="rerenderThis"> instead of the actual tags , there are several unwanted behaviours if you rerender a tag with dynamic attributes and such.


In your case


<apex:outputPanel id="oopsPage">
<apex:form rendered="{!renderMe}">



This way the rendered attribute of your form is re-checked each time you rerender, otherwise its not.

To make it a bit more clear imagine the Rerender only rerendering the contents of the tag, not the tag itself.
