Because your relationship from author to books is a to-many relationship.
This makes sense, because an author can have many books.
So authorItem.books is actually an array of Books. And
authorItem.books.title is actually an array of book titles---an array of
all the titles of all the books owned by that author. So when you output
it, you get the String representation of such an array.
In this case, it's just got one book in it, so it looks like ("Title"). If
it had more books, it would look like ("Title1", "Title2", "Title3").
What you want to do is, not output the String representation of an Array,
but instead use a WORepetition to step through each book in the author's
book array, and then print out the title of each book, seperated however
you want. Each one in a seperate table row, seperated by HTML BR to put
each on a different line, whatever.

Hi -- I hope you will all forgive my dumb questions for a while as I struggle
a bit.
I created an entity "author", and an entity "book", and I have a relationship
from author to book joined by an authorID attribute. The book entity has an
attribute "title". On my web page, I can display authorItem.books.title, but
why does it appear in quotes surrounded by parentheses?
(e.g. it shows as '("Big Book")' instead of just 'Big Book' in my table
cell?
