Dear members,
Today I tried to "Build and Run..." a rule base that i created some time ago and executed correctly. Now I get the error "Object reference not set to an instance of an object." when I try to execute the rule base using Oracle Web Determinations (the build is still succesful). When I execute the rule base using "Build and Debug..." no errors are presented and the rule base is executed succesfully as well. I can also access the rule base in my web browser without having any problems. I expect that the cause of the problems lay in the recent installation of Google Chrome and / or Mozilla Firefox, yet I don't know where to look for a solution. I already tried to install the latest version of Oracle Policy Modeling, but the error hasn't been resolved by that.
