rspec users - Sep 2010 - passing a block to a stub method

It seems that rspec doesn''t support passing a block to a stub method.
This code fails:

def call_build_with_block(o)
  o.build do
    puts "hello"
  end
end


describe "call_build_with_block" do
  it "should call build with block" do
    o = double("object")
    o.should_receive(:build) do |&b|
      b.should_not be_nil
      block_given?.should == true
    end

    call_build_with_block(o)
  end
end

Anybody?

What you can use is the "and_yield" method:

o.should_receive(:build).and_yield do |eval_context|
  eval_context.should_not be_nil
end

Hope that helps.
