Views is unable to tell when profile.module adds new fields

Ok, so the problem here is that profile.module has no hook which Views can use to know when profile fields have changed.

This means that you need to clear the cache in order for Views to see profile fields after you modify them.

This was actually addressed in the original post, but there IS a lot of text there and I sympathize that it might be difficult to figure that out amongst the rest of the chatter. Unfortunately this is a weakness of profile.module and there isn't anything Views can do about it.

The easiest way to clear the Views' cache is to go to your administer >> modules page and click 'submit'. Views will see that and know to clear the cache.
