After rowedit the value should be affect the db and also it should be displayed in the datatable

I am very new born babie for Datatable. I use roweditor. But the problem is, the value is it not displaying after an edit was made in some rows. Sometimes the database was not changed as well. I use update query. Can anyone help me?
Thanqu in advance.
here is my code:
public void onRowEdit(RowEditEvent event)
{
System.out.println("hello...");
detail_li.clear();
FacesMessage msg = new FacesMessage("row Edited",selected_bean.get_name());// i have doubt here
FacesContext.getCurrentInstance().addMessage(null, msg);
DBQuery db = new DBQuery();
String code=selected_bean.getCode();
String Student_name = selected_bean.getStudent_name();
System.out.println(" code$..."+code);
String Student_name = selected_bean.getStudent_name();
String rank = selected_bean.getRank();
String feedback = selected_sngbean.getFeedback();
int res = db.special_code(rank,feedback,code);//here used update query
detail_li = db.detaillist(class,code,student_name);
}
This is my datatable code..

Java Primefaces how to work with elements placed in dataTable column header

When "selectOneMenu" is placed in the "dataTable" column header it:
1) triggers row sorting everytime it is opened or after the button next to it is clicked and "selectOneMenu" is opened (it shouldn't be like that);
2) fails to assign value to the backing bean.
How can "selectOneMenu" be attached to the column header so that these problems wouldn't occur?
*.xhtml code with dataTable which causes 1) and 2) problems:
<h:form id="someForm0">
<p:dataTable id="sdt" var="variable" value="#{otherBean.tableModel}" rows="10">
<p:column sortBy="#{variable.name}" filterBy="#{variable.name}" filterMatchMode="contains" >
<f:facet name="header">
<h:outputText value="Name"/>
<h:panelGrid columns="2" cellpadding="1">
<p:selectOneMenu id="abc" value="#{userBean.someChars}">
<f:selectItem itemLabel="" itemValue="select" />
<f:selectItem itemLabel="AAA" itemValue="AAA" />
<f:selectItem itemLabel="BBB" itemValue="BBB" />
<f:selectItem itemLabel="CCC" itemValue="CCC" />
</p:selectOneMenu>
<h:commandButton id="btn" value="Submit" type="submit" action="#{userBean.submitChars}"/>
</h:panelGrid>
</f:facet>
<h:outputText value="#{variable.name}"/>
</p:column>
</p:dataTable>
</h:form>
Backing bean code:
#ManagedBean
public class UserBean
{
private String someChars;
public String getSomeChars()
{
return someChars;
}
public void setSomeChars(String someChars)
{
this.someChars = someChars;
}
public String submitChars()
{
if(getSomeChars() != null)
{
System.out.println("Selected chars are: " + getSomeChars());
}
else
{
System.out.println("Selected chars are equal to null!");
}
return null;
}
}
Here is fragment of the previously mentioned *.xhtml code, and selectOneMenu works just great when placed into the basic form:
<h:form id="someForm">
<p:selectOneMenu id="abc" value="#{userBean.someChars}">
<f:selectItem itemLabel="" itemValue="select" />
<f:selectItem itemLabel="AAA" itemValue="AAA" />
<f:selectItem itemLabel="BBB" itemValue="BBB" />
<f:selectItem itemLabel="CCC" itemValue="CCC" />
</p:selectOneMenu>
<h:commandButton id="btn" value="Submit" type="submit" action="#{userBean.submitChars}"/>
</h:form>
I think the last resort would be adding elements from the dataTable column header to the dataTable header:
<h:form id="someForm1">
<p:dataTable id="sdt" var="variable" value="#{otherBean.tableModel}" rows="10">
<f:facet name="header">
<h:panelGrid columns="2" cellpadding="1">
<p:selectOneMenu id="abc" value="#{userBean.someChars}">
<f:selectItem itemLabel="" itemValue="select" />
<f:selectItem itemLabel="AAA" itemValue="AAA" />
<f:selectItem itemLabel="BBB" itemValue="BBB" />
<f:selectItem itemLabel="CCC" itemValue="CCC" />
</p:selectOneMenu>
<h:commandButton id="btn" value="Submit" type="submit" action="#{userBean.submitChars}"/>
</h:panelGrid>
</f:facet>
<p:column sortBy="#{variable.name}" filterBy="#{variable.name}" filterMatchMode="contains" >
<f:facet name="header">
<h:outputText value="Name"/>
</f:facet>
<h:outputText value="#{variable.name}"/>
</p:column>
</p:dataTable>
</h:form>

Try as below :
<h:form id="someForm0">
<p:dataTable id="sdt" ...>
<p:column headerText="header">
<p:selectOneMenu id="abc" value="#{userBean.someChars}">
<f:selectItem itemLabel="" itemValue="select" />
<f:selectItem itemLabel="AAA" itemValue="AAA" />
<f:selectItem itemLabel="BBB" itemValue="BBB" />
<f:selectItem itemLabel="CCC" itemValue="CCC" />
<p:ajax event="valueChange" update=":someForm0:sdt"/>
</p:selectOneMenu>
</p:column>
</p:dataTable>
<h:commandButton ....>
</h:form>
UserBean.java
private String someChars;
public String getSomeChars() {
return someChars;
}
public void setSomeChars(Stirng someChars) {
this.someChars = someChars;
}

Primefaces 3.5 SNAPSHOT datatable push (websocket) update

I'm using Mojarra, PF 3.5 SNAPSHOT, Tomcat 7.0.32 and trying to make a datatable update itself when changes have been done by other clients. I'm also using CDF beans along with MyCODI, #ViewAccessScoped.
When I was using 3.4, in-row editing (instead of in-cell editing) and standard #ConversationScoped it was working.

Your table id is staffTable not ba_staffTable

CDI params in #PostConstruct

I think my question is similar to this but haven't found it to work
<f:metadata>
<f:viewParam id="id" name="id" value="#{detailsBean.id}"/>
</f:metadata>
Why can't I do this with #Named and utilize CDI:
#Named
#RequestScoped
public class DetailsBean {
private Contacts detailsContact;
#EJB
ContactsFacade contactsEJB;
private int id;
public DetailsBean() {
System.out.println("details bean called");
}
#PostConstruct
public void onLoad() {
detailsContact = contactsEJB.find(id);
}
I'm not able to log the id.
Of course, #ManagedProperty is incompatible with CDI.

The inputText boxes populate fine. But soon as I hit submit it says that the values are null. This code works perfectly with SessionScope.
WARNING: /admin/index.xhtml #104,109 value="#{detailsBean.detailsContact.name}": Target Unreachable, 'null' returned null
javax.el.PropertyNotFoundException: /admin/index.xhtml #104,109 value="#{detailsBean.detailsContact.name}": Target Unreachable, 'null' returned null
I can see that it's calling the EditBean when I select the data table. It then calls it again when I click the submit button.

I encountered the exact same problem than you, and solved it by using the external context (containing GET parameters) instead of f:viewParam.
In your #PostConstruct method, just get your parameter with something like
FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap();

The lifecycle doesn't allow your approach.
At first, the bean is created ( constructor ). After that, there is executed dependency injection which is followed by #PostConstruct method and after that the JSF file is evaluated. And the viewParam is in that file. So you have to register another listener which is called after filling view params.
I have a solution for #RequestScope beans, but if the bean's scope is longer ( like View ) then this method is executed after each request ( including AJAX ) which is not probably desired.
Use this for request scope beans:
<f:metadata>
<f:viewParam id="id" name="id" value="#{detailsBean.id}"/>
<f:event type="preRenderView" listener="#{detailsBean.onLoad}" />
</f:metadata>
For #ViewScope beans I am using this "hack" which works but probably is not best practise. It does same thing but probably it isn't the correct approach.
#{detailsBean.onLoad()}
<f:metadata>
<f:viewParam id="id" name="id" value="#{detailsBean.id}"/>
</f:metadata>
I hope that this is helpful for you.
EDIT:
you are using a lot of AJAX here. This calls have to land in at least ViewScoped beans. View Scope is similar to RequestScope, but it takes a quite longer - til the page is left.
But I haven't read it all, there is a lot of code and if the ViewScope doesn't help then maybe you should provide the small piece of problematic code to be chance there to find and focus on the real problem.
