Goal

When checking your WLS Log files, you see warnings like the following:

<RegionRenderer> <encodeAll> The region component with id: <yourRegionID> has detected a page fragment with multiple root components.
Fragments with more than one root component may not display correctly in a region and may have a negative impact on performance.
It is recommended that you restructure the page fragment to have a single root component.
