Hi, I 've been throught the tutorial with one thing I can't figure out

first part is OK : creating HOmePage typer and templates/HomePage.ss works fine

when I get in trouble is here :

the tutorial says "SilverStripe first searches for a template in the tutorial/templates folder. Since if there is no HomePage.ss, it will use the Page.ss for both Page and HomePage page types. When it comes across the $Layout tag, it will then descend into the tutorial/templates/Layout folder, and will use Page.ss for the Page page type, and HomePage.ss for the HomePage page type"

my problem is that when I delete templates/HomePage.ss, the Layout/HomePage.ss is rendered alone, without the template/Page.ss template around it

any idea why is that ? thanks
