The problem is that overridden method load() in my LazyDataModel implementation is being called twice every time I try to filter the table.
My LazyDataModel implementation:
public class LazyPostDataModel extends LazyDataModel<Post> {
private List<Post> data;
private final PostService postService;
public LazyPostDataModel(PostService postService) {
this.postService = postService;
data = new ArrayList<>();
}
#Override
public Post getRowData(String rowKey) {
Long id = Long.valueOf(rowKey);
for (Post p : data) {
if (p.getId().equals(id))
return p;
}
return null;
}
#Override
public Object getRowKey(Post post) {
return post.getId();
}
#Override
public List<Post> load(int first, int pageSize, String sortField, SortOrder sortOrder, Map<String,Object> filters) {
PostFilter filter = new PostFilter(filters, first, pageSize);
FilteredDataModel<Post> postDataModel = postService.findFilteredList(filter);
data = postDataModel.getData();
this.setRowCount(postDataModel.getCount().intValue());
return data;
}
}

And the controller

#SessionScoped
#Transactional(Transactional.TxType.REQUIRED)
public class ModeratioPostController extends BaseController implements Serializable {
#Inject PostService postService;
private LazyPostDataModel posts;
// Selection
private Post selected;
#Override
protected void initSpecific() {
posts = new LazyPostDataModel(postService);
}
// Actions
public void approve() {
if (selected == null) return;
Post post = postService.find(selected.getId());
post.setModerationApproved(Boolean.TRUE);
postService.edit(post);
}
public void reject() {
if (selected == null) return;
Post post = postService.find(selected.getId());
post.setModerationApproved(Boolean.FALSE);
postService.edit(post);
}
public LazyPostDataModel getPosts() {
return posts;
}
public void setPosts(LazyPostDataModel posts) {
this.posts = posts;
}
public Post getSelected() {
return selected;
}
public void setSelected(Post selected) {
this.selected = selected;
}
}
this is because you have
filterBy="#{post.moderationApproved}"
and
<p:selectOneButton onchange="PF('ModerationPostTable').filter()">
both of these will call the filter once and cause the load method to be called twice.
Use one of them only.

i am pretty new to jsf and i'm having a bit trouble implementing a subTable in my dataTable. Der var atribute from my subtable doesn't seem to evaluate to the elements from the list. Also the #PostConstruct method from my backing bean isn't called either, when i execute my webapp and navigate to the xhtml site. No errors are shown in the console, so i have pretty much no idea what i did wrong.

Manager Class fills the Database with some initial data, so there is nothing really interesting going on.
JSF version is 2.2.12 and PrimeFaces version is 6.0.
I'm using Maven for build and the webapp is running on GlassFish 4.1.1.
the problem I have is that the command button in my dialog doesn't fire the action method in the controller. No logger outputs for the example method "greet". Can anybody look over please and give me hints? What am I doing wrong?

you need actionListener attribute instead of action in your p:commandbutton tag. and Also use #ViewScoped instead of #SessionScoped in your backing bean. and add ajax="false" in p:commandButton
First of all I know some other similar questions about my title, but My issue is a little bit different... When I try to initialize LazyDataModel in my #ViewScoped Bean it works fine until I click the actionButton on my page. When My Bean is created, its #PostConstruct method works as expected and LazyDataModel filled up in that method then datatable populated well. But when ajax called by actionButton in my page then entire bean recreated and #PostConstruct method called again, with that LazyDataModel value changing to null. Because of that, my page is crashing. In another scenario I was using rowSelect event in my datatable instead of actionButton with method which has a SelectEvent parameter. In SelectEvent parameter object field of it was null and I was getting NullPointerException. These are the scenarios... As result I guess when I use LazyDataModel in my #ViewScoped bean It calls PostConstruct again and my datamodel returns null for my SelectEvent method.
This is my ViewScoped PostConstruct method

When I clicked a row of Datatable selectEvent.getObject() --> NULL always with LazyDataModel.
A big important information: These all situations happens in WebLogic 10.3.6.0 and works on TomCat like charm (even with LazyDataModel).
My Development environment: JSF 2.0, Primefaces 5.2, Liferay 6.2.3 ga4 with TomCat 7.04.
Testing environment: Same all except WebLogic 10.3.6.0 (Problem only occurs on here)
I really appreciate if someone could help me... Thanks in advance!!!
EDIT:
#ManagedBean (name = "myEctrInboxBB")

public class MyEContractInboxBackingBean implements Serializable {
private static final long serialVersionUID = 2399679621562918360L;

}
We can access Spring Beans like that:
public EContractProcessService geteContractProcessService() {
ELContext elContext = FacesContext.getCurrentInstance().getELContext();
return (EContractProcessService) FacesContext.getCurrentInstance().getApplication()
.getELResolver().getValue(elContext, null, "eContractProcessService");
}
I have created a complexe dataTable for my DiplomeBean and it shows Correctly
The deal is whene i select a row from the list ,nothing happend
I want whene i select a row it shows me the elements of the diplome.

Thank's :)
Perhaps try modifying it slightly to be more like the Primefaces showcase example. For example, try something like this:
...
<h:form id="form">
...
<p:dataTable value="#{diplome.getAllDiplome()}" var="d" paginator="true" rows="10"
rowKey="diplome.idDiplome" selection="#{diplome.selectedDiplome}" selectionMode="single">
<p:ajax event="rowSelect" update=":form:display" oncomplete="PF('diplomeDialog').show()" />
...
</p:dataTable>
...
<p:dialog header="Diplome Detail" widgetVar="diplomeDialog" resizable="false"
width="200" showEffect="explode" hideEffect="explode">
<h:panelGrid id="display">
...
</h:panelGrid>
</p:dialog>
</h:form>
...
I can't test this right now, but it seems like it should work since it is essentially the same as the showcase's example.
I'm using an editable Primefaces p:datatable to show the data to the user. In this datatable, I have a p:column with a h:selectOneMenu, and another one with a p:selectBooleanCheckbox.
I want to check or uncheck and disable or enable the checkbox depending on the value selected in the h:selectOneMenu.
If I only had one h:selectOneMenu and one p:selectBooleanCheckbox, I'd use a p:ajax to attach a listener to the change event, and I'd manipulate the p:selectBooleanCheckbox in this method. But I have a pair of h:selectOneMenu and p:selectBooleanCheckbox per row and I don't know how to do this.
This is what I tried:
<h:form>
<p:dataTable var="appointment" value="#{prescController.appointmentsToday}" editable="true" id="tblAppointments">
<p:ajax event="rowEdit"
listener="#{prescController.onEdit}" update=":messages" />
<p:column sortBy="presc.drug" headerText="Drug">
<p:cellEditor>
<f:facet name="output">
<h:outputText value="#{appointment.presc.drug.name}" />
</f:facet>
<f:facet name="input">
<h:selectOneMenu value="#{appointment.presc.drug}"
converter="#{drugConverter}" required="true">
<f:selectItem itemLabel="" noSelectionOption="true" />
<f:selectItems value="#{prescController.drugs}"
var="drug" itemLabel="#{drug.name}" />
<p:ajax update="autoAmount" />
</h:selectOneMenu>
</f:facet>
</p:cellEditor>
</p:column>
<p:column sortBy="presc.autoAmount" headerText="Auto amount">
<p:cellEditor>
<f:facet name="output">
<h:outputText value="Y"
rendered="#{not empty appointment.presc.drug.rules and appointment.presc.autoAmount}" />
<h:outputText value="N"
rendered="#{empty appointment.presc.drug.rules or not appointment.presc.autoAmount}" />
</f:facet>
<f:facet name="input">
<p:selectBooleanCheckbox id="autoAmount"
value="#{not empty appointment.presc.drug.rules and appointment.presc.autoAmount}"
disabled="#{appointment.presc.drug.name eq 'somethingsomething'}" />
</f:facet>
</p:cellEditor>
</p:column>
<p:column>
<p:rowEditor />
</p:column>
</p:dataTable>
</h:form>
The post Retrieving other component's client ID in JSF 2.0 describes how to retrieve ids of other components in a page. In my opinion, the #{p:component('sampleButton')} should find the next component having this ID in the component tree - this should be the same row.
Alternatively, you should be able to rerender the whole row via JSF 2 #{component.parent.clientId} functionality (measure out, how many "parent" steps you need, e.g. #{component.parent.parent.clientId}).
Hope it helps, else just add comments... :-)
I can't imagine why you are unsatisfied with simple update="checkboxId"but what you can try is updating component through widgetVar which you can generate during page render.
Tiny example:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<title>Table Example</title>
</h:head>
<h:body>
<h:form prependId="false">
<p:dataTable var="data" value="#{tableBean.data}">
<p:column headerText="Command">
<p:commandButton value="Toggle" actionListener="#{tableBean.toggleSelection(data.id)}"
update="#widgetVar(tableCheckboxComponent_#{data.id})" />
</p:column>
<p:column headerText="Value">
<h:outputText value="#{data.value}" />
</p:column>
<p:column headerText="Selected">
<p:selectBooleanCheckbox widgetVar="tableCheckboxComponent_#{data.id}" value="#{data.selected}" />
</p:column>
</p:dataTable>
</h:form>

Backing bean:
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
#ManagedBean
#ViewScoped
public class TableBean {
private Map<String, MyData> data;
public List<MyData> getData(){
return new ArrayList<MyData>(data.values());
}
public TableBean() {
data = new HashMap<String, MyData>();
for (int i = 0; i<22; i++) {
String id = "id" + Integer.toString(i);
data.put(id, new MyData( id , i));
}
}
public void toggleSelection(String id) {
MyData myData = data.get(id);
myData.setSelected(!myData.isSelected());
}
}
And Data object:
public class MyData {
private String id;
private boolean selected;
private int value;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public int getValue() {
return value;
}
public void setValue(int value) {
this.value = value;
}
public boolean isSelected() {
return selected;
}
public void setSelected(boolean selected) {
this.selected = selected;
}
public MyData(String id, int value) {
this.id = id;
this.value = value;
this.selected = false;
}
}
I still don't know why my approach didn't work.
In the end, I added a listener to the p:ajax component to manipulate the SelectBooleanCheckbox in the managed bean
<p:ajax listener="#{prescBean.onDrugSelected}" update="autoAmount" />
public void onDrugSelected(AjaxBehaviorEvent event) {
Drug drug = (Drug) ((UIOutput) event
.getSource()).getValue();
boolean hasRules = drug.getRules().size() > 0;
SelectBooleanCheckbox cbAutoAmount = (SelectBooleanCheckbox) ComponentUtils
.findComponent(FacesContext.getCurrentInstance().getViewRoot(),
"autoAmount");
cbAutoAmount.setDisabled(!hasRules);
cbAutoAmount.setValue(hasRules);
}
