You cannot assign a value to a bound variable. $c is bound to the field name of a PassThrough fact object.

Assigning values to regular variables can only be done in the consequence, e.g.,

then
   String s = hello("r");
   ...
end

You can use the modify statement (in the consequence) to change a field of some fact object.

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
