To be able to access globals within functions
---------------------------------------------

                 Key: JBRULES-969
                 URL: http://jira.jboss.com/jira/browse/JBRULES-969
             Project: JBoss Rules
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: All
         Environment: Drools version 3.0.6, Using Eclipse IDE and simple DRL file working with Global variables
            Reporter: Natraj Gudla
         Assigned To: Mark Proctor


Hello,
 
I am using Drools 3.0.6. While using a global variable in a function, the compiler complains it cannot resolve the global variable name. Something like below
 
global com.sample.ExampleLogger customLogger; 

function void logMessage(String msg){ 
customLogger.logMessage("Log Message from the function"); 
}

In the above code, it complains "customLogger cannot be resolved". I am able to refer the global in the consequence of a rule directly. What is the problem using the reference within a function. 
 
On the other hand, i am able to do something like
  
function void logMessage(ExampleLogger custLogger,String msg){
custLogger.logMessage(msg+" Accept gloabal as function parameter"); 

}
and call from the consequence of a rule : logMessage(customLogger);  // I am passing the global to the function as an argument and then use it to log a message. 
This way is working. But not the first way of using the global in the function. It would be a good feature to have the globals accessible within functions.
