Hi folks,

The examples in trunk show this exact same behavior.

It seems the examples have been neglected a little bit, since I first  
had to upgrade them from 0.3.0 --> 0.3.1. The attached patch shows the  
changes I made.

Scenario to get to the NPE:
1) apply patch
2) mvn clean install  - compiles claims example till html-viewer (json  
viewer fails)
3) cd html-viewer
4) mvn jetty:run
5) open browser in http://localhost:8080/claims-viewer-html
6) login
7) click Employees
8) click New Employee
9) Enter a name
10) click save ----> NPE

Regards,

Minto
