[rules-users] using variables in eval

[rahulkrishnan]

Hi

1.i have a rule like this 
rule "Function Call"
dialect "mvel" 
	when
		PassThrough( $c : name)
		eval(($c = hello("rahul"))!=null)
	then
		System.out.println($c);
		
end
 in this my function will return the string as capital and am entering to
the consequence part but the $c is printed as null. am not getting what is
happend. 

And if i want to assign the result of function call to a String declared as
(String s) how can it be done
