Bug with Custom Component Rerender inside apex:repeat

I seem to have run into a bug with custom components trying to rerender parts of themselves: The rerendered component is able to display updated values as text, but formula evaluations of any updated values ignore the updated values and instead use initial values.

For example: Let's say I have a component has an apex:inputText with value="{!accountName}" that rerenders the parent apex:outputPanel during an onchange event. After rerendering, a few odd things happen:

• The apex:inputText reverts to blank control.
• If I display {!accountName} as text, the new value appears fine.
• Any other components that have rendered="{!NOT(ISNULL(accountName))}" are still not rendered.

An experience is worth a million words, so I've put up a demo in my sandbox.  The source code for the demo is also available.

1. In the Lead (standalone) section, enter something into the Name field.
2. Click somewhere else on the page.  An Ajax refresh will occur, and the Text Insertions and Output Component Renders section should correctly update to reflect the new Name value.
3. Now, in any Lead (from List) section, enter something into the Name field.
4. Click somewhere else on the page.  An Ajax refresh will occur.
5. Observe two problems:  The Name field is blanked out, and the Output Component Renders section did not change.

Hopefully, Salesforce Premier Support will tell me that the problem will be fixed immediately within the next 5 business days.  Hopefully...
