Could not find element(s) after scrolling using swiping up to refresh the list

Appium 1.3.5, iOS 8.1, Mac OS Yosemite, Xcode6.1.1

The app has a page that has a list of items (UIATableCell classType), due to having many items, the list can be scrolled until the last item is shown by swiping up. When my test navigates to the page, it is able to grab the list using:
List elementList = driver.findElements(By.name(“eventItem”));

That works fine until I scroll the page down using swipe function to swipe upward based on coordinates. After scrolling to the last item in the list, the test performs the same call again, but this time, “eventItem” is not found.

Anyone has similar issue, and way to work around?
