Chapter List not Updating
When adding/removing chapters from a book, the chapter list doesn't always reflect the change. Also when renaming a chapter, the book may not reflect the change. The most serious effect is when the URL changes, we get a 404 error.
Fixed in Alpha 2. This required adding a vw_blockcacherelation table which keeps track of cache elements containing page info and clears those cache items whenever the pages are updated.
