file upload problem null
Hi everyone,
I Am trying to develop a relatively Web 2.0 application, and 6 days ago I faced a problem with <s:fileUpload> tag. I get null for my byte array holding data and also for a contentType. I checked that even setters aren’t called. I wanted to see what is in the request so I added my own filter wrapped around Seam MultipartFilter. It shows basic info about request. Every time I send a request (except request from logging page) the length of request is -1 and contentType is null. I am really confused and stuck for good. I hope somebody will know how to solve this issue. I suspect the answer will be trivial.
Here is my form
<s:validateAll>
<h:form id="UploadPhotoForm" enctype="multipart/form-data">
<fieldset>
<s:decorate id="imageField">
<s:fileUpload id="imageData" accept="image/*"
data="#{upload.imageData}"
contentType="#{upload.imageContentType}"
fileName="#{upload.title}" />
</s:decorate>
<s:button id="save" value="Upload" action="#{upload.savePicture}"/>
</fieldset>
</h:form>
</s:validateAll>And my action
@Name("upload")
@Scope(ScopeType.PAGE)
@Local
public class UploadPictureAction implements Serializable
{
@In
User user;
@Logger
Log log;
private static final long serialVersionUID = 1L;
private byte[] imageData;
private String imageContentType;
private String title;
public byte[] getImageData()
{
return imageData;
}
public void setImageData(byte[] imageData)
{
this.imageData = imageData;
System.out.println("Value:"+imageData);
}
public String getImageContentType()
{
return imageContentType;
}
public void setImageContentType(String imageContentType)
{
this.imageContentType = imageContentType;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public void savePicture()
{
PicturesManager pm = PicturesManager.getInstance();
try
{
System.out.println("imageContentType:"+imageContentType);
System.out.println("imageData:"+imageData);
}
catch(Exception e)
{
log.error(e.getMessage(),e);
}
}

Additionaly my filter
@Startup
@Scope(ScopeType.APPLICATION)
@Name("UploadFilter")
@BypassInterceptors
@Filter(around="org.jboss.seam.web.multipartFilter")
public class ErasmusUploadFilter extends AbstractFilter
{
public void doFilter(ServletRequest arg0, ServletResponse arg1,FilterChain arg2) throws IOException, ServletException
{
HttpServletRequest httpRequest = (HttpServletRequest) arg0;
System.out.println("[UploadFilter] ContentLength:"+httpRequest.getContentLength());
System.out.println("[UploadFilter] ContentType:" + httpRequest.getContentType());
Enumeration a = arg0.getAttributeNames();
while(a.hasMoreElements())
{
Object elem = a.nextElement();
System.out.println("[UploadFilter] Atribute:" + elem + " wartosc:" + arg0.getAttribute((String)elem));
}
for(Object e: arg0.getParameterMap().keySet())
{
System.out.println("[UploadFilter] Parameter:"+ e.toString());
}
arg2.doFilter(arg0, arg1);
}
}
