Hello dear list, I currently have problems to access global variables in a drools 5.1 bpmn rule-flow. I have a script-task at the end of my process-flow in which I want to call a method of an "external" service. I instantiated the service and set it as global in the ksession before starting the process. In the script-task I add global x.y.z.MyService myService with the same name as setted before and call the object with the method with script-type mvel/java: myService.xyz(); Is this the right way doing this? Because I'm receiving the error-message "cannot access variable with name 'myService'" or similar (can't remember exactly). When adding the service as a "process variable" in the model and then starting the process, I can access this variable in the script-task... but - I think using globals would be much nicer for accessing the service in some of my rules in the same way under the same variable. After all I also don't know how to access modified process-variables in my task. For example if I change some object in a rule-task before and in a script-task later I want to call a service with the modified object... do I have to read a process variable in the rule, modify it and then in the script-task I access the process-variable or could I access the changed object in the working-memory in the script-task as well? Like or similar because this is just rule-style: when $o : MyObject (withMyChangedParameter == 'x') then service.myMethod($o); TIA Björn Diese E-Mail kann vertrauliche und/oder rechtlich geschützte Informationen enthalten.
