fileUpload - problem updating model
I am attempting to create a simple form in my application that allows the user to upload an image and store it in the database.
When the form is submitted after the image is selected I am getting the following exception:
16:26:23,936 WARN [lifecycle] executePhase(UPDATE_MODEL_VALUES 4,com.sun.faces.context.FacesContextImpl@32ba35) threw exception
javax.el.PropertyNotFoundException: /super/SkinEdit.xhtml @18,24 data="#{skinHome.instance.skinBanner}": Property 'skinBanner' not writable on type [B

}Here is my form page:

I have setup my components.xml with:
<component class="org.jboss.seam.web.MultipartFilter"> <property name="createTempFiles">true</property> <property name="maxRequestSize">4194304</property> </component>
and my web.xml with:
<filter> <filter-name>Seam Filter</filter-name> <filter-class>org.jboss.seam.servlet.SeamFilter</filter-class> </filter> <filter-mapping> <filter-name>Seam Filter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
Can anyone spot why my model can't be updated properly?
Much appreciated.
