[opencms-dev] Exception when locking & editing file

[denisboutin at free.fr]

Hi,

I've got the following exception when I want to lock & edit a page. It was 
working very well then it throws an exception

I've got :
* tomcat 5.0
* jdk1.4.1_01
* OpenCMS v5.0.1

Have you got an idea to resolve this problem ?

Regards,
Denis.
