Is there a process for using Detail Group Regions?

Question

Hi Guys,
I have a question regarding dynamically displaying stacked detail groups. I want to display a detail group depending on a value that is set in the master group.
The documentation surrounding the Detail Group Regions is vague. Is there a set process on how to do this or even a documented case on how to get it to work? We have tried using Detail Group Regions but when we did the form of the master group was not displayed.

Steven,
Below is a stripped down version of my app def including the group layout settings. Even with no rendered expression only the relationship and address detail groups appear (person and organization are missing), and instead of the SeachDetails/SearchCriteria form fields the organization table appears above the detail groups.
If I create detail group regions for all four detail groups then no detail groups are displayed and its the address table that appears instead of the form fields.
