<!--</h:commandButton>-->
</h:form>
</h:panelGrid>
</ui:define>
And my Backing Bean Code is as
@Named("patchingBean")
@ViewScoped
public class PatchingBackingBean implements Serializable {
ObjectFactory objFactory= new ObjectFactory();
private List<Property> propertyList=null;
@PostConstruct
public void init(){
System.out.println("Creating the initial data once don't repeat");
propertyList=new ArrayList<Property>();
Property prop=objFactory.createProperty();
prop.setName(CommandParamName.PLAN.toString());
propertyList.add(prop);
System.out.println("Size of the list " + propertyList.size());
}
public List<Property> getPropertyList() {
return propertyList;
}
public void setPropertyList(List<Property> propertyList) {
this.propertyList = propertyList;
}
public String addProperty() {
System.out.println("Adding the data into the
list************************");
propertyList.add(objFactory.createProperty());
System.out.println("size of list after getting added "+
propertyList.size());
return "AddedProperty";
}
I am not getting System.out.println() of addProperty() Method on Server
Log , i.e my addProperty method is not being called when i click on Add
button .
Kindly Help....
