Add

  no-loop true

on the line after the "rule" directive.



rule "1"
no-loop true

[rules-users] How do I access objects in a top level or condition?

[Chidambaran Subramanian]

rule "Test"
  dialect "mvel"
  when
( Customer( age == 50 ) or Deal( amount == 30 ) )
  then
Customer.setAge( "40" );
update( Customer );
Customer.setPlace( "Test" );
update( Customer );
end



Appreciate any help in this regard.
