What I mean is that my object has:
set index_page "en:index"
my en:index page is
This is a repository with our cast pages.
>left-col<<
{{adp portlets/categories {name {Table of Contents} tree_name Cast}}}
><<
Now the page named index shows up on the index page in each category.
i.e.
show
index
glenwood springs.
personal
index
newsletter
index
I believe the problem may be that if you require a category your index page also needs to have a category and that makes it part of it's own index.
This is more a UI issue and an annoyance than a bug, I hope you understand the problem.
