This error suggests that your 'vw_book' table doesn't have a 'book_childlist' column. Please double-check this.

Although it could also mean that the book was already fetched by page rather than by book, and for some (bug) reason, the page was cached without the corresponding rows from 'vw_book'.

EDIT: I see the problem. There is a design flaw: the fetcher will return a 'page' if we ask for a 'book' (expected), but will still return the page even if it is not a book.

In vault/core/controller/dm/item/chapter/vw.php, find:

Code:

if ($prevbook)

Replace with:

Code:

if ($prevbook AND !empty($prevbook['book_childlist']))

I am trying to resolve that design flaw now but doing so causes other problems.

Fixed this design flaw in the next release.

The fetcher will now only return a result from cache if the cache entry matches the filter being requested.
e.g. When searching for page with pageid = 9 and searching for book with pageid = 9, the latter will no longer product a result if pageid = 9 is not a book.
