PeopleSoft and Invalid Views in the Oracle Database

I was listening to the section on Invalid Views in PSADMIN Podcast #117 (@19:00). Essentially, when you drop and recreate a view that is referenced by a second view, the status on the second view in the database goes invalid. This is not a huge problem because as soon as you query the second view it is compiled. However, you would like to know whether any change to a view prevents any dependent views from compiling, although you would expect have teased these errors out before migration to production.
