Hi

I am using betwixt in combination with Torque (Turbine DB-layer) in 
order to generate XML, which is used for transforming XSL stylesheets to 
HTML.

Somewhere during the process of transforming the Torque beans to XML I 
get a NullPointerException from betwixt code. See the short versions of 
stack trace and the Log4j DEBUG output below.

I do not know if the exception is a bug in betwixt since I believe that 
betwixt can handle object values that are null.

Any help would be appreciated.
