Uploading file throws No signature of method exception (in getFile() method)

Question

Im trying to upload a file, and store it in a file. This is the code in the GSP:

<g:form method="post" enctype="multipart/form-data"  action="update">
<input type="file" name="cv" id="cv"/>
<g:actionSubmit action="upload" name="upload" value="Upload" />
</g:form>

In the Controller:

def upload(){
def f = request.getFile('cv')
InputStream file = f.inputStream
byte[] bytes = file.bytes
println('bytes: '+bytes)
}

As I say in the title, i got an exception here. Any help? Thanks.

EDIT (Full Stacktrace, by request):

I have tried the code and it works for me, don't see anything wrong there. — Dopele, Jan 10 '13 at 13:50
I don't see anything wrong, neither, but the exception keeps happening. Grails version issue, maybe? Im on 2.0.4 — Fustigador, Jan 10 '13 at 13:56
Please, provide full stacktrace to be sure what happens here. — Isammoc, Jan 10 '13 at 15:07
It could be a config issue, here are a few tips that may help: http://jira.grails.org/browse/GPSPRINGSECURITYCORE-191 — Andrew, Jan 10 '13 at 18:46
I have checked the config.groovy, and my grails.web.disable.multipart is set to false. — Fustigador, Jan 11 '13 at 09:33
@Fustigador did you ever solve this? Having the same exact issue here? — Aaron, Nov 09 '15 at 10:50
@Aaron, I can't remember. I asked this almost three years ago, and I can't even remember if I managed to solve it. Sorry buddy... — Fustigador, Nov 09 '15 at 11:04
@Fustigador thanks anyway, i know it was long time ago :) answer below didn't seem to work either :( — Aaron, Nov 09 '15 at 11:32

The problem is that your request is not treated as a MultiPartRequest. Do something like this:

MultipartRequest multipartRequest =  request as MultipartRequest
  if(multipartRequest){
    MultipartFile attachmentFile = multipartRequest.getFile("attachment_file".toString())
    if (attachmentFile) {
        -- copy it ---
    }
  }
