I am trying to break my page into multiple components so it can be reused on several pages. The component is essentially a form and after submission, would like the parent page to rerender a certain outputpanel block. This is the code I used to use:

<apex:actionFunction name="reRenderNewFeedPanel" action="{!afterSaveAttachment}" reRender="NewFeedPanel, FeedListPanel" />

but from within the component, the reRender on "FeedListPanel" doesn't seem to work, because it's not refreshing.
