I hadn't picked up the validateNow() tip yet; thanks for providing a
more complete answer!

There are a couple stategies that may work in different circumstances.
For example, calling executeBindings(true) will force all bound data
to requery their sources which essentially updates your view if it's a
form and/or if it's the data you really want to refresh.
However, if you just want the entire layout to repaint without regard
to refreshing data bindings, the sure fire way is this:
invalidateDisplayList();
validateNow();
The first call to invalidate the display list *might* result in the
view refreshing, but it only marks the view as needing a refresh and
doesn't always immediately do so.
By calling validateNow() after invalidating your display list, you are
"forcing" the UI to repaint immediately. I think that's probably what
you meant when you said you wanted to "force" a refresh.
You can see this pattern used all over the Flex SDK.
