visual web JSF page--jsp and design out of sync

I have a JSF visual web page, and I copy/pasted something from another page into the JSP view. Seemed faster than drag-and-drop-and-drag-and-drop-and-drag-and-drop. But now the design view doesn't show that part. Neither does the navigator window. Am I hosed? Do I need to throw away the page and redo it from scratch? Or is there a way to force synchronization?
