hi everibody:
I am working to upload images to the server and guide me with the fileupload component of the page
http://livedemo.exadel.com/richfaces-demo/richfaces/fileUpload.jsf?c=fileUpload&tab=usage RichFaces
Example guide works well in GlassFish v2, the problem occurs when I switch to GF V3 (the app up, load the image but when I give click on the button "clear uploaded data" of <h:form> I get the following error (java.lang.NullPointerException).
Below I will paste the error trace.
I debugged my app and detect where the error is when the button "clear uploaded data" called the event "string clearUploadData" in class "FileUploadBean" and the method returns null.
if someone could help me would be very, very grateful.
My development environment is: netbeans 6.9, RichFaces 3.3.3, JSF 1.2, Java EE 5 web, oracle 10g client
PS: Sorry for my English
below the stack of error:
java.lang.NullPointerException
