--------------------------------------

you must pass your globals specifically as a parameter.

>      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

> 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.
