Consider the following files : 1)Dynamo_rules_test.java 2)Manager.java 3)
ForAllManager.java 4)BooleanWrapper.java 5)StringWrapper.java
6)NumberWrapper.java -----------------------------------------------------
and consider two simple rules: rule "Regola 3" agenda-group "b2"; salience
3; no-loop true; when f2 : ForAllManager( id == "b2") && n1 :
NumberWrapper(id=="n1") && eval(n1.getValue() < 100) then System.out.println
(n1.getValue()); retract(n1); if(f2.getCursor().hasNextSelection() == true)
f2.esegui(); else {assert (new BooleanWrapper(f2.getId(),true);
retract(f2);} end rule "Regola 3.x" agenda-group "b2"; salience 3; no-loop
true; when f2: ForAllManager( id == "b2") && n1 : NumberWrapper(id== "n1")
&& eval(!(n1.getValue() < 100)) then assert(new
BooleanWrapper(f2.getId(),false));
retract(n1); retract(f2); end When the system has to assert the object
BooleanWrapper in the WorkingMemory, I get the following errors:
