I have a <h:selectBooleanCheckBox> as part part of my JSF which I want to run a bean method when it's state has changed from unchecked to checked.
I have the following controller bean
#Named
#ViewScoped
public class UserController {
#Inject
private UserService userService;
#Inject
private LocationService locationService;
private UserFilter userFilter;
private List<User> users;
private List<Location> locations;
#PostConstruct
public void init() {
users = userService.listAll();
locations = locationService.listAll();
userFilter = new UserFilter();
}
public List<User> getUsers() {
return users;
}
public void setUsers(List<User> users) {
this.users = users;
}
public List<Location> getLocations() {
return locations;
}
public void setLocations(List<Location> locations) {
this.locations = locations;
}
public void listAllUsers() {
users = userService.listAll();
}
public void findUsers() {
// code that uses the UserFilter
// to decide which user filter find method to use
}
}
The UserFilter is a simple DTO
public class UserFilter {
private boolean allUsers = true;
private String username;
private String location;
//getters and setters
}
And my JSF has is like so
<?xml version='1.0' encoding='UTF-8' ?>

As you can see by default it lists all users, then when the checkbox is unchecked you have the option to filter on username/location.
What I want is for the check box to run the userController.listAllUsers() method when it's state moves from unchecked to checked.
And a small additional question, how do I get the checkbox to appear in the same row as the panel grid items?
I have a habit of answering my own questions it seems! I needed an additional <f:ajax tag that rendered the user form and had the listener attribute set
So something like
<h:selectBooleanCheckbox id="selectAll" value="#{userController.userFilter.allUsers}" title="allUsers">
<f:ajax render="filterGrid"/>
<f:ajax render="usersForm" listener="#{userController.listAllUsers()}"/>
</h:selectBooleanCheckbox><h:outputText value ="All users"/>

I've one table embedded into another table. My problem: How to render only the inner table when a row was removed?
Bean:
#Named
#ViewScoped
public class TestBean implements Serializable {
private static final long serialVersionUID = -5633666299306108430L;
private List<String> strLst1;
private List<String> strLst2;
#PostConstruct
public void init() {
strLst1 = Arrays.asList("a", "b", "c");
strLst2 = Arrays.asList("d", "e", "f");
}
public List<String> getStrLst1() {
return strLst1;
}
public List<String> getStrLst2() {
return strLst2;
}
public void removeFromStrLst2(String val) {
strLst2.remove(val);
}
}

My problem is the Ajax-render attribute which doesn't get the correct id (examples for the first row):
innerTableContainer leads to mojarra.ab(this,event,'action',0,'innerTableContainer') It doesn't work!
innerTable leads to mojarra.ab(this,event,'action',0,'form:outerTable:0:innerTable:0') It doesn't work!
#parent leads to mojarra.ab(this,event,'action',0,'form:outerTable:0:innerTable:0:j_idt14') It doesn't work!
#namingcontainer leads to mojarra.ab(this,event,'action',0,'form:outerTable:0:innerTable:0') It doesn't work!
#form works but this isn't I was looking for.
The correct and working id would be form:outerTable:0:innerTableContainer but how to get it?

I have a JSF page with a h:selectManyList and a Primefaces commandButton. I want to add new elements to the list when I click the button. The button's action method is called, but elements don't show up in the list. I probably just don't see the forest for the trees.

Why doesn't the added item appear in the list and what do I need to do to make it appear?
You reversed the fields in the xhtml.
<h:selectManyListbox id="listBox" value="#{testBean.availableThings}" style="width:100%">
<f:selectItems value="#{testBean.selectedThings}"/>
</h:selectManyListbox>
Should be
<h:selectManyListbox id="listBox" value="#{testBean.selectedThings}" style="width:100%">
<f:selectItems value="#{testBean.availableThings}"/>
</h:selectManyListbox>
I thought I'd try and get a primefaces datagrid working with my JSF code, but I always got "no results found". So I'm trying to set up a simple example but I get the same error messages so I must be doing something fundamentally wrong.
I have the following backing bean:
#ManagedBean
#ViewScoped
public class CarBean {
private static final Logger logger = Logger.getLogger("datagrid.ejb.CarBean");
private List<Car> cars;
public CarBean() {
cars = new ArrayList<Car>();
cars.add(new Car("myModel",2005,"ManufacturerX","blue"));
logger.log(LogLevel.INFO, "added car");
//add more cars
}
public List<Car> getCars() {
return cars;
}
public void setCars(List<Car> cars) {
this.cars = cars;
}
}
And the following xhtml page:
<!DOCTYPE html>
<html xmlns="http://www.w3c.org/1999/xhtml"
xmlns:h="http://xmlns.jcp.org/jsf/html"
xmlns:p="http://primefaces.org/ui">

<h:body>
<p:dataGrid var="car" value="#{carBean.cars}" columns="3"
rows="12"layout="grid">
<p:column>
<p:panel header="#{car.model}">
<h:panelGrid columns="1">
<p:graphicImage value="/images/cars/#{car.manufacturer}.jpg"/>
<h:outputText value="#{car.year}" />
</h:panelGrid>
</p:panel>
</p:column>
</p:dataGrid>
</h:body>
</html>
I can see from the logs and debugger that the CarBean is instantiated but still I get the no records found error. Any ideas?
Thanks,

#ViewScoped beans are alive per view. If you open a popup window from your current view, then you're opening a new view, so even if it uses the same managed bean to display the data, since they're different views, they use different instances of the same class.
In cases like this, you should pass a parameter through query string, then receive it in your view and process it to load the desired data. In this case, your code would be like this (note: make sure you send the parameter with name "urunId"):

How to choose the right bean scope?
DataTable expects a list to iterate through, but as far as I can see you return an UrunIcerik object.
I have a JSF 2 form like this:
<h:form>
<h:panelGrid columns="2">
<a4j:repeat value="#{dialog.departments}" var="depart">
<h:inputText value="#{depart.name}"/>
<h:selectOneRadio value="#{depart.hasSubdepartment}">
<f:ajax render="#form" execute="#form" immediate="true"/>
<f:selectItem itemValue="#{true}"/>
<f:selectItem itemValue="#{false}"/>
</h:selectOneRadio>
<a4j:repeat value="#{depart.subdepartments}" var="sub" rendered="#{depart.hasSubdepartment}">
<h:inputText value="#{sub.name}"/>
<h:outputText value=" " />
</a4j:repeat>
</a4j:repeat>
</h:panelGrid>
</h:form>
I have simply the form. As you could see, this form displays data structure of departments like a tree.
What I want to implements is that if user switch the radio button to true, the sub-departments will be displayed, if switch to false, the sub-departments will be hidden.
The problem is that:
If the execute value of the f:ajax tag is set to #form, the validation of the backing beans such as #NotNull and #Size will be called. But we don't want to call the validation now since we do not want to save the data now.
If the execute value of the f:ajax tag is set to #this, it seems that the after the ajax request, the value of the radio reverts. For example, if the radio value is false, and we click true, then after the ajax request, the value go back to false, and the sub-department part is not rendered. This will not happen if execute is set to #form.
Thanks very much if you have any idea or hint.
I don't have a Richfaces integrated testing environment, however I've achieved what you want in plain JSF (that's why it could be an ajax4jsf specific issue). Here you have a test case which works and follows SSCCE standards. Tested with Mojarra 2.1.26 & Tomcat 6:
