Database activity module: Create default templates when creating activity

I created a new database activity, added a single field, add an entry, save and display shows "Single template is not yet defined". I would think that when creating the activity or perhaps when we get to the point where there is not single template defined that we use or construct a generic default display. Then if the user does not like it they can change it. This appears to be the behavior for view list and add entry so it seems strange that we do not do the same for view single. Peace - Anthony
