I am working through chapter 10 of Ravi Mendis' WebObjects Developer's
Guide. The Home page that is created on pages 168/169 has a display
group based on the "Forum" EO. A forum has one to many topics which in
turn have one to many posts. In the example, the WORepetition "list" is
bound to the forumDisplayGroup.displayedObjects. The "item" is bound to
the key "forum" which is of type "Forum".
In WOBuilder when I select the "forum" key (in the lower left hand side
of the screen) it displays the attributes for name and topics but when
I select "topics", all I see are aggregate variables such as count,
avg, etc. I don't see any further links to "posts". Mendis shows a
screenshot with two WOStrings: one bound to the value for
forum.topics.count and another bound to forum.topics.posts.count. The
posts array is not showing up in WOBuilder and if I type in the binding
as written, it doesn't display the posts count for the topic. That
string also shows the topics count when I load it in a browser. Does
anyone have any idea why that might be? Is what Mendis' screenshots
show even possible? Thanks,
David
