public void onSubtypLvllTypValChnge(ValueChangeEvent valueChangeEvent) {

        valueChangeEvent.getComponent().processUpdates(FacesContext.getCurrentInstance());

Thanks Lakshman for your comments.
Including your comments in the post for the benefit of others.

2)

We can also use
java.util.ResourceBundle rb = ResourceBundle.getBundle("com/oracle/,,,,/Bundle1");
String txt = rb.getString("prop1");

3)
public String readPropertiesFile(String property){
String configureURL = null;
try{
InputStream is = ConfigureBean.class.getResourceAsStream("Engenio.properties");
Properties prop = new Properties();
prop.load(is);
configureURL = prop.getProperty(property);
is.close();
/* code to use values read from the file*/
}catch(Exception e){
e.printStackTrace();

}
return configureURL;
}

Getting old/previous value of an ADF BC attribute

Getting old/previous value of an attribute notes from the Source  Oracle Insider Article

Groovy expression to get old value:

1) Create a transient attribute and generate eoimpl or voimpl. Override the getter method with the following

return getPostedAttribute(model.EmployeeImpl.SALARY)

Posted value is which is submitted.

2) To use as part of validations we can use implicit objects available as part of groovy expression.

sample:

newValue - OldValue < oldValue *.1
