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?

    <apex:detail relatedList="false" />

Hi Matt,
 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="{!}" relatedList="false" />


Thanks Ron. Adding the subject parameter to my detail fixed that issue right up.

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?

It looks like you have two different forms on one Visualforce page. 

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.
