So on 3.2.1 and before if I wanted to do this I would add the route create a "show" or similar function have it return the customise info and create the template and done I can now display my DataObject using getURLParameters().
If I try and do this in 3.3 I can't get the template to display. It just ignores it and uses the base page.ss template. If I downgrade to 3.2.1 and change nothing about my code it all works as expected.
I am assuming something changed along the way just not sure what.
Thanks for any help.
