my pb is that when I select an item to display items in the second selectOneMenu () the submit button does not work.
at the second click the button tries to submit the form but (this action emptie the second SOM) as the second SelectOneMenu becomes empty its trigger a validation error.

I'm working on a project that requires a dataTable for each item of a collection, and each of those dataTables has dynamic columns.
Here's an example of what I want to do..

Thank you all!
Value of p:columns cannot refer to var of parent dataTable. Documentation http://www.primefaces.org/showcase/ui/data/datatable/columns.xhtml shows this moment. Actually in your model each row can contain different number of columns. You need to change model:
TableModel:
package test;
import java.util.ArrayList;
import java.util.List;
/**
* Created by kit on 14.12.2015.
*
* #author kit
*/
public class TableModel {
private String name;
private List<RowModel> rows = new ArrayList<>();
private List<ColumnModel> columns = new ArrayList<>();
/**
* Getters, Setters
*/
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public List<RowModel> getRows() {
return rows;
}
public List<ColumnModel> getColumns() {
return columns;
}
}
RowModel:
package test;
import java.util.HashMap;
import java.util.Map;
/**
* Created by kit on 14.12.2015.
*
* #author kit
*/
public class RowModel<T> {
private String name;
private Map<ColumnModel, T> data = new HashMap<>();
/**
* Getters, Setters
*/
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Map<ColumnModel, T> getData() {
return data;
}
}
ColumnModel:
package test;
/**
* Created by kit on 14.12.2015.
*
* #author kit
*/
public class ColumnModel<T> {
private T data;
/**
* Getters, Setters
*/
public T getData() {
return data;
}
public void setData(T data) {
this.data = data;
}
}

Identifying and solving javax.el.PropertyNotFoundException: Target Unreachable
(18 answers)
Closed 7 years ago.
I got this error below when I was running my JSF page.
javax.el.PropertyNotFoundException: Target Unreachable, 'null' returned null..
Warning: /createStaff.xhtml #33,125
value="#{staffBean.staff.firstName}": Target Unreachable, 'null'
returned null javax.el.PropertyNotFoundException: /createStaff.xhtml
#33,125 value="#{staffBean.staff.firstName}": Target Unreachable,
'null' returned null
I don't get why I will run into the error when I use value="#{staffBean.staff.firstName}". There is no problem when I use the value="#{staffBean.userName}" and value="#{staffBean.passWord}" above.
This is my createStaff.xhtml

You have no property firstName in your entity staff
UPDATE:
Looks like your staffobject is null add:
#PostConstruct
public void init() {
staff = new Stuff();
}
The error suggests that when the "firstName" is being accessed, it cannot be reached. So the "Staff" has not been constructed yet.
Add a method to your managed bean, this will resolve the issue.
#PostConstruct
public void init() {
staff= new Staff ();
}
For better understanding of why you should do it that way and not
Staff staff = new Staff();
JSF - what is the difference between #PostConstruct and direct method call from constructor?
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;
}
}

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.
