Thanks in advance ~ :)
Exactly Primefaces follows strict structure and I think it is compulsory to add init() method with @PostConstruct annotation.
@PostConstruct
public void init(){
userTypeMasters = userTypeMasterDAO.getAllUserTypes();
}
Here is the solution.
package com.convoy.gpack.managedbean;
import java.io.Serializable;
import java.util.List;
import javax.annotation.PostConstruct;
import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.context.FacesContext;
import org.apache.log4j.Logger;
import org.primefaces.event.RowEditEvent;
import com.convoy.gpack.dao.UserTypeMasterDAO;
import com.convoy.gpack.pack.models.UserTypeMaster;
@ManagedBean(name = "userTypeTabMenuBean")
@SessionScoped
public class UserTypeTabMenuBean implements Serializable {
private static final long serialVersionUID = 1467465633405172689L;
private static final Logger logger = Logger
.getLogger(UserTypeTabMenuBean.class);
private List<UserTypeMaster> userTypeMasters;
private UserTypeMasterDAO userTypeMasterDAO = new UserTypeMasterDAO();
private UserTypeMaster selectedUserType;
private String userType;
// This is the required method to get the datatable list.
@PostConstruct
public void init() {
userTypeMasters = userTypeMasterDAO.getAllUserTypes();
logger.info("getUserTypeMasters=" + userTypeMasters);
}
public List<UserTypeMaster> getUserTypeMasters() {
return userTypeMasters;
}
public String deleteAction(UserTypeMaster userTypeMaster) {
logger.info("Deleting the object with id = " + userTypeMaster.getId());
UserTypeMasterDAO userTypeMasterDAO = new UserTypeMasterDAO();
int result = userTypeMasterDAO.deleteUserType(userTypeMaster);
userTypeMasters.remove(userTypeMaster);
if (result == 1) {
FacesMessage msg = new FacesMessage(
"User type deleted successfuly.");
FacesContext.getCurrentInstance().addMessage(null, msg);
} else {
FacesMessage msg = new FacesMessage("Failed to delete user types.");
FacesContext.getCurrentInstance().addMessage(null, msg);
}
return null;
}
public void onRowEdit(RowEditEvent event) {
UserTypeMaster userTypeMaster = (UserTypeMaster) event.getObject();
logger.info("UPDATING THE USER TYPE MASTER : "
+ userTypeMaster.getType());
UserTypeMasterDAO userTypeMasterDAO = new UserTypeMasterDAO();
userTypeMasterDAO.saveOrUpdateUserTypeMaster(userTypeMaster);
logger.info("UPDATING THE USER TYPE MASTER : "
+ userTypeMaster.getType());
FacesMessage msg = new FacesMessage("Edited type ",
((UserTypeMaster) event.getObject()).getType() + "");
FacesContext.getCurrentInstance().addMessage(null, msg);
}
public void onRowCancel(RowEditEvent event) {
FacesMessage msg = new FacesMessage("Editing Cancelled for ",
((UserTypeMaster) event.getObject()).getType() + "");
FacesContext.getCurrentInstance().addMessage(null, msg);
}
public UserTypeMaster getSelectedUserType() {
return selectedUserType;
}
public void setSelectedUserType(UserTypeMaster selectedUserType) {
this.selectedUserType = selectedUserType;
}
public String getUserType() {
return userType;
}
public void setUserType(String userType) {
this.userType = userType;
}
public void saveAction() {
logger.info("Saving the object to database...." + userType);
if (userType.trim().length() < 1) {
FacesMessage msg = new FacesMessage("Can not save empty user type.");
FacesContext.getCurrentInstance().addMessage(null, msg);
}
UserTypeMasterDAO userTypeMasterDAO = new UserTypeMasterDAO();
UserTypeMaster userTypeMaster = new UserTypeMaster();
userTypeMaster.setType(userType);
int result = userTypeMasterDAO
.saveOrUpdateUserTypeMaster(userTypeMaster);
if (result == 1) {
FacesMessage msg = new FacesMessage("User type saved.");
FacesContext.getCurrentInstance().addMessage(null, msg);
init();
} else if (result == -2) {
FacesMessage msg = new FacesMessage("User type already exist..");
FacesContext.getCurrentInstance().addMessage(null, msg);
} else {
FacesMessage msg = new FacesMessage("Failed to save user type.");
FacesContext.getCurrentInstance().addMessage(null, msg);
}
}
}
That's it~ :)
Thanks @Swathi for the hint.
