NullPointerException while UploadItem.getData() in <rich:fileUpload>

[elenaveretilo]

Hi all! I have one more problem(

I want to use <rich:fileUpload> example from:

http://livedemo.exadel.com/richfaces-demo/richfaces/fileUpload.jsf?tab=usage&cid=1447304

But I get NullPointerException while UploadItem.getData() in FileUploadBean.java:

public void listener(UploadEvent event) throws Exception{
 UploadItem item = event.getUploadItem();
 File file = new File();
 file.setLength(item.getData().length);
 file.setName(item.getFileName());
 file.setData(item.getData());
 files.add(file);
 uploadsAvailable--;
 }  

item.getData() - throws NullPointerException.

Here is my xhtml page:

What could be wrong?

Please - I need your help as soon as possible!

Thanks and good luck!

check CREATE_TEMP_FILES context param in developer reference guide.

Hi, thanks for quick reply!

I didn't find anything about CREATE_TEMP_FILES context param, but I found out about init-param for RichFaces filter!

I add <init-param> creataTempFiles to RichFaces filter definition and everything works fine)

     <!-- Defining and mapping the RichFaces filter -->
     <filter>
          <display-name>RichFaces Filter</display-name>
          <filter-name>richfaces</filter-name>
          <filter-class>org.ajax4jsf.Filter</filter-class>
          <init-param>
                  <param-name>createTempFiles</param-name>
                  <param-value>false</param-value>
            </init-param>
     </filter>

Is that a correct solution? Or I need to work with CREATE_TEMP_FILES context param?

And one more question - the button "Add" disabled if I add the number of files = uploadsAvailable (for my case it's only one file), and if I click "clear" - this button is still disabled. How can I set it enable, when I click "clear" link?

Thanks!

sorry my mistake in naming init-param as context-param Your way is correct now.
