Something that i haven't thought about before but need to do now... I have noticed that features do not have the attribute to "reevaluate condition" like components do.
Are features naturally transative or are they incapable of being transative? In otherwords if I reinstall a product will the install level condition on the feature be retested and uninstall unnecessary features and install new features?
Conditions on features only work to set install levels, and install levels only work to set a default for whether the feature is installed. Once a user selects a set of features (either by accepting the defaults, or by customizing them) and installs these, install levels and thus conditions on features make no further difference. By contrast, a component's condition is evaluated after it's known that an associated feature will be installed (or remain installed for the transitive case).
So in short features don't have anything like a component's transitive flag. If you want to change the features that are installed, look towards properties and control events like ADDLOCAL, AddLocal, REMOVE and Remove.
