Save checkbox state After ReLoadThe Page in JSF Primefaces - primefaces

Im using a "DataTable - Selection",(http://www.primefaces.org/showcase/ui/data/datatable/selection.xhtml) in primefaces 5 to check the selected rows, but when I reload the page, the checkboxes are unchecked, How can i keep the state of the checkboxes in session?
**
*********DataTable****************
**
<p:dataTable var="var" value="#{vistaBean.listaFichero}" rowKey="#{var.nombre}" paginator="true" rows="10"
selection="#{vistaBean.selectFichero}">
<f:facet name="header">
Votar ProductBox
</f:facet>
<p:column headerText="Votar" selectionMode="multiple"/>
<p:column headerText="Nombre del Fichero">
<h:outputText value="#{var.nombre}" />
</p:column>
<p:column headerText="Ver/Descargar">
<h:commandLink id="pdf" action="#{vistaBean.downLoad}">
<f:setPropertyActionListener target="#{vistaBean.ruta}" value="#{var.ruta}" />
<h:graphicImage library="images" name="pdf.png" />
</h:commandLink>
</p:column>
</p:dataTable>
<p:commandButton value="Guardar Votos" action="#{vistaBean.addVoto()}" update="msgs"/>
<p:commandButton value="Ver Votos" update="display" oncomplete="PF('dlg').show()" icon="ui-icon-check" inmediate="true"/>
<p:dialog header="Product Box Seleccionados" modal="true" showEffect="clip" widgetVar="dlg" resizable="false">
<p:outputPanel id="display">
<p:dataList value="#{vistaBean.selectFichero}" var="v">
#{v.nombre}
</p:dataList>
</p:outputPanel>
</p:dialog>

I solve the issue by installing a newer version of Primefaces, 5.2, i had the 5.1 and it had that bug.

This is how you set a session variable:
FacesContext facesContext = FacesContext.getCurrentInstance();
HttpSession session = (HttpSession) facesContext.getExternalContext().getSession(true);
session.setAttribute("foo", "bar");
This is how you can get session variables:
FacesContext facesContext = FacesContext.getCurrentInstance();
HttpSession session = (HttpSession) facesContext.getExternalContext().getSession(false);
Enumeration e = session.getAttributeNames();
while (e.hasMoreElements())
{
String attr = (String)e.nextElement();
System.err.println(" attr = "+ attr);
Object value = session.getValue(attr);
System.err.println(" value = "+ value);
}
Your only task is to save the state of your checkboxes into the session and then load it.

Primefaces dataTable columns sequence by displayPriority parameter

I try to change Primefaces dataTable columns sequence using displayPriority parameter. But it does not work.If I try to change isVisible parameter or Width parameter of column everything works fine, but displayPriority does not work, why?
My xhtml:
<p:dataTable id="dataTableIncomingDoc"
var="item"
scrollable="true"
scrollHeight="100%"
scrollWidth="100%"
showGridlines="true"
selectionMode="single"
draggableColumns="true"
resizableColumns="true"
size="small"
styleClass="fixed-size"
selection="#{docsBean.docEntitySelected}"
rowKey="#{item.id}"
value="#{docsBean.loadDocsList()}">
<p:column id="registrationDate"
headerText="Reg. date"
width="100"
filterBy="#{item.registrationDate}"
sortBy="#{item.registrationDate}"
filterMatchMode="contains">
<h:outputText value="#{item.registrationDate}"/>
</p:column>
<p:column id="regNr"
headerText="Reg. Nr."
width="100"
filterMatchMode="contains"
sortBy="#{item.regNr}"

filterMatchMode="contains"
sortBy="#{item.docNr}"
filterBy="#{item.docNr}">
<h:outputText value="#{item.docNr}"/>
</p:column>
</p:dataTable>
My bean:
public List<DocEntity> loadDocsList() {
var dataTable = (DataTable) FacesContext.getCurrentInstance().getViewRoot().findComponent("mainForm:dataTableIncomingDoc");
var a = dataTable.getColumns().get(1);
var b = dataTable.getColumns().get(2);
((Column) a).setDisplayPriority(2);
((Column) b).setDisplayPriority(1);
PrimeFaces.current().ajax().update(dataTable);
return docsList;
}

In Cell editing does not update value on focus change

Cell value is not captured when mouse focus changes
I have a simple datatable that shows the name and income. The cell values are editable. When I update the cell value with a different value and hit "Update" (basically change mouse focus) the new value is not captured. The update method
prints the old value. However, when I press the "tab" key I can see the updated values printed. I am not sure what I am missing
Here is my backing bean:
#PostConstruct
public void init() {
NVPair nvp = new NVPair("xx", 10000);
dataList.add(nvp);
nvp = new NVPair("yy", 20000);
dataList.add(nvp);
}
public void update() {
for (NVPair item : dataList) {
System.out.println("Name: " + item.getName() + " Value: " +
item.getValue());
}
}
Here is the view:
<h:form>
<p:dataTable id="testTable" value="#{testBean.dataList}" var="item"
editable="true" editMode="cell">
<p:ajax event="cellEdit" listener="#{testBean.onCellEdit}"
immediate="true" update="testTable" />
<p:column headerText="Name">
<p:cellEditor>
<f:facet name="output">
<h:outputText value="#{item.name}" />
</f:facet>
<f:facet name="input">
<h:outputText value="#{item.name}" />
</f:facet>
</p:cellEditor>
</p:column>
<p:column headerText="Income">
<p:cellEditor>
<f:facet name="output">
<h:outputText value="#{item.value}" />
</f:facet>
<f:facet name="input">
<p:inputText value="#{item.value}" />
</f:facet>
</p:cellEditor>
</p:column>
</p:dataTable>
<p:commandButton action="#{testBean.update}" value="Update" />
</h:form>
When the focus changes, I am expecting that the edited value is captured just like when the tab key is pressed.

PrimeFaces <p:cellEditor> not changing value of variable

I've done some research and haven't been able to find anything that directly addresses the problem I've been having.
I have a DataTable column that is editable (by cell) and I have the ability to click on the cell, enter a new number in the cell editor box, but when I hit the cell editor closes but does not save the new value (same thing happens if you just click off and don't hit enter).
Here is the Code Snippet
<h:form>
<c:forEach items="#{extensionsBean.getPhases()}" var="phase">
<p:fieldset legend="#{phase.getPhaseName()}">
<p:dataTable value="#{extensionsBean.getActivities(phase)}" var="activity" editable="true" editMode="cell">
<p:column>
<f:facet name="header">
<h:outputText value="Actual Hours"/>
</f:facet>
<p:cellEditor>
<f:facet name="output">
<h:outputText value="#{activity.getEstimateDetail().actualHours}"/>
</f:facet>
<f:facet name="input">
<h:inputText value="#{activity.getEstimateDetail().actualHours}" />
</f:facet>
</p:cellEditor>
//the rest of the closing tags are present
Any suggestions would be great! For the record, I have basically the exact same setup in a different xhtml page and I'm able to edit each of the cells without a problem. Not sure what's causing this one to bug out on me.
Add Ajax event cellEdit and store the values
Add ajax event celledit and where do you want save the value you can save it.
Code is below in my project
Xhtml page(Primefaces):
<p:dataTable var="my" value="#{java.custom_info}" editMode="cell" editable="true" style="font-size: 12px">
<p:ajax event="cellEdit" listener="#{java.custom_detail}"/>
<p:column style="background: white">
<h:outputText value="First Name"/>
</p:column>
<p:column style="background: white">
<p:cellEditor>
<f:facet name="output"> <h:outputText value="#{my.first}"/> </f:facet>
<f:facet name="input"><p:inputText value="#{my.first}" placeholder="Enter First Name" style="width:93%"/></f:facet>
</p:cellEditor>
</p:column>
</p:dataTable>
Java Class
public void custom_detail(CellEditEvent event){
String old_str = (String) event.getOldValue();
String first_name = (String) event.getNewValue();
System.out.println("update method reached..."+first_name);
FacesContext fc = FacesContext.getCurrentInstance();
HttpSession session = (HttpSession) fc.getExternalContext().getSession(false);
Query db = new Query();
Customer bean = new Customer();
if(session!=null){
if(((String)session.getAttribute("login"))!=null){
Calendar currentDate=Calendar.getInstance();
SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String datenow=format.format(currentDate.getTime());
session.setAttribute("firstname", first_name);
session.setAttribute("modified_date",datenow);
bean.setFirst(first_name);
bean.setUsrid((String)session.getAttribute("user"));
bean.setUsr_modified(datenow);
db.update_personalinfo(bean);
}
}
}

Primefaces ActionListener not fired if h:inputHidden in the datatable

I am using Primefaces 5.1 and have this strange behaviour.
If in my dataTable I have h:inputHidden then mymethod() is not fired.
The method is fired if I remove it.
<p:dataTable id="tablerisorse" value="#{myBean.resources}" var="resource"
rowStyleClass="#{(rowIndex mod 2) eq 0 ? 'oddRow' : 'evenRow'}"
rowIndexVar="rowIndex"
emptyMessage="Empty" headerClass="header">
<p:column>
<h:inputHidden id="id_user" value="#{resource.user}"/>
<f:facet name="header">
<h:outputText value="Surname"/>
</f:facet>
<h:outputText value="#{resource.surname}" />
</p:column>
<p:column>
<p:commandLink id="linkdet" actionListener="#{myBean.mymethod}" ajax="false"onstart="progressbar()" oncomplete="hideprogressbar()">
<p:graphicImage value="images/res.png" style="{border: 0}"></p:graphicImage>
</p:commandLink>
</p:column>
</p:dataTable>
the method is:
public void impegnirisorsa(ActionEvent ae) {
// TODO Auto-generated method stub
HtmlInputHidden uicid_user = (HtmlInputHidden) ae.getComponent().findComponent("id_user");
String id_user = ""+uicid_user .getValue();
System.out.println("id_user"+id_user);
}
I wonder what the problem could be and which workarounds could I use.

Primefaces dialog fields not filled after click in CommandLink

I am using Primefaces 3.5 with Weblogic 11. I have a page where a dialog to edit a 'profile' entity ('perfil' in Portuguese) which is called from two places. First from a commandButton to insert a new profile. The second from a dataTable to edit a specific profile. Below, I show the code:

What is my problem? Apparently, when I want insert a new Profile, all seems OK. However, when I click to edit an existent profile to open the dialog, although the outputText and pickList are correctly filled, the inputText's and selectOneMenu are not.
Looking for solutions, I found here a suggestion to use appendToBody="true" in dialog. When I tried, the inputText's and selectOneMenu are correctly filled. However, the validation is not working as waited. When I click to save it is showed a message indicating that pickList is not filled, even if it is really filled. Actually, even if inputText's are not filled, there is no message about these inputTexts although they are required.
Another alternative would be use <f:setPropertyActionListener> inside commandLink:
<!-- OPEN DIALOG TO CREATE A NEW PROFILE -->
<p:commandButton id="btnIncluir" value="Incluir"
update="dlgPerfil" immediate="true"
actionListener="#{perfilAcessoMB.abrirDialogoEdicao}"
oncomplete="dlgPerfil.show();">
<f:setPropertyActionListener target="#{perfilAcessoMB.perfil}" value="#{null}"/>
</p:commandButton>
<!-- OPEN DIALOG TO EDIT A NEW PROFILE -->
<p:commandLink id="lnkEditar" immediate="true"
title="Editar Perfil" update=":formPrincipal:dlgPerfil :formPrincipal:pnlPerfilEdicao"
actionListener="#{perfilAcessoMB.abrirDialogoEdicao}"
oncomplete="dlgPerfil.show();">
<f:setPropertyActionListener target="#{perfilAcessoMB.perfil}" value="#{perfil}"/>
<h:outputText value="Editar" />
</p:commandLink>
The actionListener method would changed to:
public void abrirDialogoEdicao() {
if(this.perfil == null) {
this.perfil = new PerfilAcessoORM();
}
System.out.println("PerfilAcessoMB.onAbrirDialogoEdicao(): "
+ this.perfil);
// The rest remains the same ...
}
Now, when I click to create a new perfil, although in actionListener method the perfil attribute is filled, I got a NullPointerException when the dialog is renderized. It is like first is called perfilAcessoMB.setPerfil(), after the dialog is opened and finally actionListener method. On the other hand, if I click to edit an existent profile, I return to initial situation.
Therefore, I am lost, without idea how to solve this issue.
Thanks,
Rafael Afonso
The solution was incredible simple: just added process="#this" to both commandButtons.
<!-- OPEN DIALOG TO EDIT A NEW PROFILE -->
<p:commandLink id="lnkEditar" immediate="true"
title="#{msg['titulo.edicao']}" process="#this"
update=":formPrincipal:dlgPerfil"
actionListener="#{perfilAcessoMB.abrirDialogoEdicao(perfil)}"
oncomplete="dlgPerfil.show();">
<h:outputText value="#{msg['titulo.edicao']}" />
</p:commandLink>
