Hi there, Im trying to list my previously defined rules but the GUI simply hangs up. This is what im doing: creation of Category [administration], then creation of package [packages], importing of my files in java packed into .jar : create new --> upload new model.jar , then im creating new rule, validating and saving it. And here comes trouble, I cannot list them when clicking on "Business rule asset" in this moments GUI freezes. http://www.nabble.com/file/p20934315/Dibujo.jpg I got apache-tomcat-6.0.16, java version "1.5.0_17", drools-5.0.0.SNAPSHOT-guvnor.zip (latest) Below you got my java file which I'm importing in jar later. Any clue people? Need help, thx in advance!!!
