Hi

I tried adding


<?xml version="1.0" encoding="iso-8859-1" ?>

on top of file and deployed the project.

On pressing coomandbutton to open dialog for file attachment, now itgives error (and dialog does not open)


It is giving Facelet exception "The processing instruction target matching 
"[xX][mM][lL]" is not allowed"

Thanks anyway for suggestion.

regards

Sandeep

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.
