AW: Trinidad: Null pointer exception in trinidad

Thu, 06 Jun 2013 00:13:00 -0700 

Hello Sandeep

The core dump says that no encoding has been set, so try to add on top of your 
xhtml file your encoding, so for example:
        <?xml version="1.0" encoding="iso-8859-1" ?>
or
        <?xml version="1.0" encoding="UTF-8" ?>

Regards,
Roland

Betreff: Trinidad: Null pointer exception in trinidad

Hi

I am using trinidad 2.0 in Jboss AS7 environment (JSF builtin Jboss) on windows 
. I am trying to upload a file to server using trinidad fileupload 
(tr:inputFile) component.

When the form is submitted to server on pressing a commandButton, I get 
Nullpointer exception. I have tried using tomahawk inputFileUpload component 
instaed of trinidad component for inputfile but the NPE remains same.

Any help/pointers to resolve this issue will be greatly appreciated.

rgds
