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:

Any ideas???
