[rules-users] Drools Flow - new variables

Hello, Is there a way to define new variables within ruleflow?. If I try to set variable that hasn't been declared in the ruleflow header - the variables section. I get following error: "Could not find variable someVariableName Continuing without setting value" I am using following code: context.setVariable("someVariableName", "someValue"); I need this for couple of reasons: - I have a custom *generic* WorkItem that has some parameters. I want to set them *dynamically* at runtime. Ideally, define new variables in onEntry and then map them with an in-mapping. - in a subflow, the subflow calculates some value, I'd like to store this value as variable and then use the out-mapping to propagate it to the parent ruleflow. I can't find any examples/test cases doing this. Is there a way to define new variables within ruleflow?. Thanking you in advance. Best Regards, Michal
