Exported function not exported correctly

Question

I am developing an R package (let's call it pkg), and I have defined a few generics. The NAMESPACE file contains both

S3method(foo, bar)
export(foo)

However, upon calling pkg::foo.bar, I get the dreaded

Error: 'foo.bar' is not an exported object from 'namespace:pkg'

I am using roxygen2, if that changes anything.

Note: If I explicitly add export(foo.bar), then everything works.

NAMESPACE (and thus exports) is only updated when you run devtools::document() - not devtools::build() or devtools::install().
