Grails upload file no signature for method getFile()

Question

I am implementing simple form with input fields and file upload. I went over tutorial: http://grails.org/Simple+Avatar+Uploader and documentation: http://grails.org/doc/2.0.x/guide/theWebLayer.html#uploadingFiles

However file upload doesn't seem to work! Why is it not working? Any solutions for the problem?

Issue:

No signature of method: org.springframework.security.web.servletapi.HttpServlet3RequestFactory$Servlet3SecurityContextHolderAwareRequestWrapper.getFile() is applicable for argument types: (java.lang.String) values: [itemImage] Possible solutions: getXML(), getPart(java.lang.String), getAt(java.lang.String), getAt(java.lang.String), getLocale(), getJSON(). Stacktrace follows: Message: No signature of method: org.springframework.security.web.servletapi.HttpServlet3RequestFactory$Servlet3SecurityContextHolderAwareRequestWrapper.getFile() is applicable for argument types: (java.lang.String) values: [itemImage] Possible solutions: getXML(), getPart(java.lang.String), getAt(java.lang.String), getAt(java.lang.String), getLocale(), getJSON() Line | Method ->> 14 | save in greatoffer.SellController$$EOVmPG4d - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - | 195 | doFilter in grails.plugin.cache.web.filter.PageFragmentCachingFilter | 63 | doFilter in grails.plugin.cache.web.filter.AbstractFilter | 53 | doFilter in grails.plugin.springsecurity.web.filter.GrailsAnonymousAuthenticationFilter | 49 | doFilter in grails.plugin.springsecurity.web.authentication.RequestHolderAuthenticationFilter | 82 | doFilter in grails.plugin.springsecurity.web.authentication.logout.MutableLogoutFilter | 895 | runTask in java.util.concurrent.ThreadPoolExecutor$Worker | 918 | run in '' ^ 662 | run . . in java.lang.Thread

Main GSP:

<g:uploadForm action="save" method="POST">
    <fieldset class="form">
        <g:render template="form"/>
    </fieldset>
    <fieldset class="buttons">
        <g:submitButton name="create" class="save" value="${message(code: 'default.button.create.label', default: 'Create')}" />
    </fieldset>
</g:uploadForm>

Image Upload part of the Form GSP:

<label for="images">
    <g:message code="item.images.label" default="Images" />
</label>

<input type="file" name="itemImage" />

Controller:

import grails.plugin.springsecurity.annotation.Secured

@Secured('permitAll')
class SellController {

    def index() {
        render(view: "seller")
    }

    def save() {
        println "Here are params: ${params}";
        def f = request.getFile('itemImage')
        flash.message = message(code: 'default.created.message', args: [message(code: 'item.label', default: 'Item'), params.id])
        render(view: "seller")
    }
}

By the type in your stack trace, the Spring Security @Secured annotation is wrapping your request in a SecurityContextHolderAwareRequestWrapper. You need to get at the MultipartHttpServletRequest to call getFile I believe.

Also, in your debug Here are params statement, are you seeing the itemImage? If so, I actually think it might be this easy.

def file = params.itemImage

UPDATE: I upvoted the comments. They weren't there when I started typing.
