Hi group, I'm running JBoss 4.2.1 (and 4.2.2, too) with shipped JSF-RI 1.2 and I want to use Tomahawk (1.1.6) <t:inputFileUpload>. I added tomahawk.jar in /server/all/deploy/jboss-web.deployer/jsf-libs because JBoss throws an error on deployment if it's missing (even if it is in my EAR and WAR). In my web.xml, I have | <filter> | <filter-name>MyFacesExtensionsFilter</filter-name> | <filter-class>org.apache.myfaces.webapp.filter.ExtensionsFilter</filter-class> | <init-param> | <param-name>uploadMaxFileSize</param-name> | <param-value>20m</param-value> | </init-param> | <init-param> | <param-name>uploadThresholdSize</param-name> | <param-value>100k</param-value> | </init-param> | </filter> | <filter-mapping> | <filter-name>MyFacesExtensionsFilter</filter-name> | <servlet-name>Faces Servlet</servlet-name> | </filter-mapping> | <filter-mapping> | <filter-name>MyFacesExtensionsFilter</filter-name> | <url-pattern>/faces/myFacesExtensionResource/*</url-pattern> | </filter-mapping> | My .jsp contains | xmlns:t="http://myfaces.apache.org/tomahawk" | (I use a lot of Tomahawk-Tags and they work with this declaration.) and | <t:inputFileUpload id="..." styleClass="..." title="#{...}" value="#{...}" valueChangeListener="#{...}" binding="#{...}" disabled="#{...}" rendered="#{...}"/> | My backing Bean has getter/setter for org.apache.myfaces.custom.fileupload.UploadedFile (getter returns null). The application is deployed as an WAR in an EAR. I have defined a loader-repository: | <jboss-app> | <loader-repository>MyApp:loader=MyApp.ear</loader-repository> | </jboss-app> | but, I tried to run it without this directive, too. After deployment and starting my application, the jsp renders a correct file-upload-control, but when I submit, I get the exception: | javax.faces.el.EvaluationException: javax.el.ELException: java.lang.IllegalArgumentException: argument type mismatch | My backing-bean setter was not called. What am I doing wrong? Doesn't Tomahawk work with JSR RI 1.2 on JBoss 4.2.x? Do I have to apply any hacks?
