Ace3 GetWidth() not working

[Racksoup]

When I try to use GetWidth() or GetHeight() on an Ace3 frame I receive the error message 'attempt to call method 'GetWidth' (a nil value)'.

local basicFrame = ACE_GUI:Create("Frame")
basicFrame:SetHeight(200)
basicFrame:SetWidth(200)
print(basicFrame:GetWidth())

When I use a frame from CreateFrame() I can use GetWidth() and GetHeight().

I am also developing on Classic if that makes a difference.
