[rules-users] Programmatically load rules classloader NullPointerException

[GrantWang]

Hello,

I was trying to build a kie module and programmatically load DRL rules at
runtime. But I found for any new event type I wanted to monitor, I had to
add "@rule(event)" when I 1st created the module. If I didn't, I would get
the following exception when I  tried to updateToVersion. My java file is
also attached. Would some one please let me know what caused my problem? And
anyway to get around this problem? We really need to get the
programmatically loading rules working in our project. Thanks a lot.
