I have this problem.
I wanted to create selectOneMenu for custom select some data. But it's not working and i really don't know why. I spent cca 5 hours with this problem. I'm so desperate.
So some my code:
But when i will pick some item from selectonemenu, selected_id is still 0. Still, still. I tried to do almost everything but without result.
I tried this:
<p:selectOneMenu value="#{medicinesBean.selectedBranch}" required="true" effect="fade" id="listComboBox">
<f:selectItems value="#{medicinesBean.branchesForComboBox}" var="itm" itemLabel="#{itm.name}" itemValue="#{itm.id}" />
</p:selectOneMenu>
Backing Bean class:
/* private members */
private ArrayList<BranchDTO> branchesForComboBox = new ArrayList<BranchDTO>();
private BranchDTO selectedBranch;
/* getter and setters ... */
also i tried this with SelectItem[] model but result was same. NOT WORK.
Then i tried it like:
<p:selectOneMenu value="#{medicinesBean.selected_id}" required="true" effect="fade" id="listComboBox">
<f:selectItem itemLabel="First" itemValue="1"/>
<f:selectItem itemLabel="Second" itemValue="2"/>
<f:selectItem itemLabel="Third" itemValue="3"/>
<f:selectItem itemLabel="Fouth" itemValue="4"/>
</p:selectOneMenu>
/* private members */
private int selected_id;
But still 0. When i used object like value for selectonemenu, always null exception was always returned. So i will be glad for any advice for this.
Thanks
brw. backing bean is ViewScoped and data from DAO are correctly returned so some bug will be in component selectonemenu.
Thanks BalusC, so here is my implementation

Remove immediate="true" from the commandButton. You are skipping the whole Apply Request Value phase - Update Model value phase with that. That's why your value is always null or 0.

I have 2 classes Games and Fouls, there are lot of fouls in a game. The user sends a parameter with the game id to find the game he want and after that the currentGame variable is created.Its type is Game. I have a datatable which prints the fouls in the current game
The setCurentGame setter is called form the body of the page onload.
so far everything works okay, but when I add a new foul, is not added to the datatable, my assumption is that the game was already retrieved (because current game was created before) so the new foul is in the database and not in the Game currentGame.
Is there any way that i can update the currentGame every time a foul i added?
I have tried refreshing the page and even to call the seeter again after creating the foul but nothing worked
The datatable looks like this:
<p:dataTable id="datalist" value="#{gameController.currentGame.foulCollection}" var="item">
<f:facet name="{exporters}">
</f:facet>
<p:ajax event="rowSelect" update="createButton viewButton editButton deleteButton"/>
<p:ajax event="rowUnselect" update="createButton viewButton editButton deleteButton"/>
<p:column width="32" sortBy="#{item.id}" filterBy="#{item.id}">
<f:facet name="header">
<h:outputText value="#{bundle.ListFoulTitle_id}"/>
</f:facet>
<h:outputText value="#{item.id}"/>

<f:facet name="header">
<h:outputText value="#{bundle.ListFoulTitle_quarter}"/>
</f:facet>
<h:outputText value="#{item.quarter}"/>
</p:column>
<p:column sortBy="#{item.foultime}" filterBy="#{item.foultime}">
<f:facet name="header">
<h:outputText value="#{bundle.ListFoulTitle_foultime}"/>
</f:facet>
<h:outputText value="#{item.foultime}"/>
</p:column>

It seems your setCurrentGame method will not be called, you can manually call it in your create() method to update the current game object from the database after the foul is created.
This question already has an answer here:
Edited/updated values in p:dataTable rowEdit are not available in listener method as they are being overwritten by existing data from database

Closed 7 years ago.
I am trying to update the row using the jsf with primefaces here is my code for each files but when I debug I am not getting updated value it gives me an old value every-time and persist it same as an old one.

Thanks in advance ~ :)
Think it might be because of the database values list
#{userTypeTabMenuBean.userTypeMasters}
this always retrieves from the database and that is why getObject() returned an old value ( actually the value from the database)
update the method getUserTypeMasters() as follows
if (userTypeMasters == null){
userTypeMasters = userTypeMasterDAO.getAllUserTypes();
}
return userTypeMasters ;
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.

i want to get answers value updated in list .please help me
Use Ajax on p:selectOneRadio to submit the answer every time user selects an answer.
<p:selectOneRadio id="options" value="#{question.answer}" >
<p:ajax event="valueChange" update="any_component's_id_you_want_to_update" />
....
....
</p:selectOneRadio>

Here is my question.When I click view button, I need to get every row of value including checkbox value whether checkbox is checked or nt then update to database. Is it possible?
How to implement a simple add/remove dynamic <rich:tabPanel>?
(I've seen people asking this around so I thought postin a Q&A of a simple implementation)
The implementation has 3 custom classes:
Content: contains the values to be displayed in a tab;
ItemTab: contais an UITab object and a Content object;
MyTabs: EJB managed bean that provides access to the tabs and adding/removal methods.
The code is:
Content:
public class Content {
String name;
String job;
String dept;
public Content() {
name = "John Doe";
job = "None";
dept = "None";
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getJob() {
return job;
}
public void setJob(String job) {
this.job = job;
}
public String getDept() {
return dept;
}
public void setDept(String dept) {
this.dept = dept;
}
}
TabItem:
public class TabItem {
UITab component;
Content content;
public TabItem() {
component = new UITab();
content = new Content();
}
public UITab getComponent() {
return component;
}
public void setComponent(UITab tab) {
this.component = tab;
}
public Content getContent() {
return content;
}
public void setContent(Content content) {
this.content = content;
}
}
MyTabs:
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import javax.annotation.PostConstruct;
import javax.enterprise.context.SessionScoped;
import javax.inject.Named;
#Named
#SessionScoped
public class MyTabs implements Serializable {
private List<TabItem> tabs;
public MyTabs() {
tabs = new ArrayList<TabItem>();
}
#PostConstruct
private void init() {
createTab();
createTab();
createTab();
}
public void createTab() {
TabItem tab = new TabItem();
tab.getComponent().setId("Tab" + (tabs.size()+1));
tab.getComponent().setHeader("Tab " + (tabs.size()+1));
tab.getContent().setName("John Doe " + (tabs.size()+1));
tab.getContent().setJob("Salesman " + (tabs.size()+1));
tab.getContent().setDept("Sales " + (tabs.size()+1));
tabs.add(tab);
}
public void removeTab(TabItem tab) {
tabs.remove(tab);
}
public List<TabItem> getTabs() {
return tabs;
}
public void setTabs(List<TabItem> tabs) {
this.tabs = tabs;
}
}
