MattL Issues with rerender
I have a VisualForce page that contains an attachment upload (basically, overriding the attachments related list). However, upon upload, the page refreshes entirely. This normally wouldn't be a problem, except that it doesn't re-render the detail, and that section is rather important to the overall flow of the page. I was under the impression that rerender would rebuild the list with a partial page refresh... however, I attempted to use this functionality when adding documents from Salesforce, and while the document is added, you don't see it in the list until you do a manual refresh. What am I doing wrong?

There is a known limitation with input File, please review Jill's comment here

your entire page should refresh, not sure why the detail page is not shown after this refresh
I can suggest that you add subject={!xx} to your detail component.
so, something like
<apex:detail subject="{!Agreement__c.id}" relatedList="false" />The other issue, however, is that it still requires another (manual) refresh for anything added to the list to show up. When the page refreshes after submitting a file from my computer, the file doesn't appear. Doing a ctrl-r on the page displays it.
Similar behavior occurs when I attempt to add a document from the Org.
Is there something I'm missing with my rerender="rows" statement?
I believe that one form is all that is needed, and it may fix the issue you describe.
I normally put one apex : form tag at the start of the page and close it at the end.
