I have a class that I declared final, has a private constructor, has only static members and methods. Some of its members are static instance of classes. In KIE-WBI added a global of that type with name X When I try to make a call on X.foo(), I get a null pointer exception. (note that x.foo() calls y.foo(), where y is a static member of X. I've read some posts that a global has to be static, am I stretching, what it means for a global to be static? I am guessing I need to write some java code that will create an instance of X and inject into working memory? I was hoping to be able to create this object within either the drools or SY framework. I have googled and be reading on this for quite a bit now, but I think I have succeeded only in confusing myself. Any help greatly appreciated. -- View this message in context: http://drools.46999.n3.nabble.com/Null-pointer-exception-when-using-globa...
