ReferenceError: ReactDOMServer is not defined

[bhernez]

Hi,

I'm kind of new using this gem, I'm starting a Rails 4.2.5 project and when I declare a component inside a .html.erb view and add the option {prerender: true} it always throws this error:

Encountered error "ReferenceError: ReactDOMServer is not defined" when prerendering COMPONENT_NAME

I'm unsure how related is this issue with this one: #443 but trying the suggested patch stops the error, but I adds another js file in the client (I don't think it is good for performance)

According to this StackOverflow post, I'm not the only one with this issue http://stackoverflow.com/questions/35200728/react-rails-component-with-prerender-true-issue

Thanks!

What's the sprockets version and sprockets-rails version in your gemfile.lock? (I think this happens for any sprockets 3 user)

@rmosolgo You are rigth about the version, I have sprockets 3.5.2 and sprockets-rails 3.0.1

Any solution for this other than downgrading sprockets? Browserify-rails is unfortunately dependant on sprockets > 3.0

Here's a workaround: #443 (comment)
Here's a fix (with breaking changes): #471

I'll try the fix too, I guess this is closed for now. Thanks!
