Hi,
I have written a simple rule:
#list any import classes here.
import test.Person
rule "check pete"
when
fet : Person( name == "pete");
then
System.out.println("fet name " + fet.getName());
end
When I run this it passes;
But If I run the same rule but in the RHS I add the person to the list,
like so:
#list any import classes here.
import test.Person
#declare any global variables here
global java.util.List list
rule "check pete"
when
fet : Person( name == "pete");
then
list.add( fet );
end
I am getting the following error
