Re: [rules-users] Drools Number to String Coercion Issue
Assuming
public class MapTest {
private Map<String,String> fields;
public Map<String,String> getFields(){
return fields;
}
}
we can write these rules
rule "test String - string"
when
MapTest( fields["String"] != null, fields["String"] ==
"10" )
then
System.out.println( "String - string" );
end
rule "test String - int"
when
MapTest( fields["String"] != null, fields["String"] == 10 )
then
System.out.println( "String - int" );
end
rule "test Integer - string"
when
MapTest( fields["Integer"] != null, fields["Integer"] ==
"20" )
then
System.out.println( "Integer - string" );
end
rule "test Integer - int"
when
MapTest( fields["Integer"] != null, fields["Integer"] == 20 )
then
System.out.println( "Integer - int" );
end
and insert one fact:
MapTest mapTest = new MapTest();
mapTest.getFields().put( "String", new String( "10" ) );
Map f = mapTest.getFields();
f.put( "Integer", Integer.valueOf( 20 ) );
kSession.insert( mapTest );
Using 5.4.0, you get
Integer - int
Integer - string
String - int
String - string
but with 5.3.0 it is
Integer - int
String - string
