When invoking a tag as a method with a body, the body object passed to the tag is no longer the original Closure, it has been wrapped up - and when you invoke it it immediately writes to out, and returns and empty string. So it appears that:

out << body()

is doing the right thing but you soon see the problem if you do this:

def b = body()
out << "This comes first" << b

You will see the body comes out before the string.

Here's a concrete Taglib example from Graeme demonstrating this:

class TestTagLib {

	def test2 = { attrs, body ->
		out << "four" << test(foo:"bar", "foo") << "five"
	}
	
	def test = { attrs, body ->
		def value = body()
		out << "one" << value << "two"
	}
}
