I am trying to use the feature of prime faces which allows user to edit the row data in the table itself.I have followed this link to achieve it:
http://www.primefaces.org/showcase/ui/datatableRowEditing.jsf
When I say edit user the new values which are entered are not sent to the bean.It still shows the old values only.
My code in JSF:
<p:dataTable value="#{mybean.userList}"
var="item"
id="dataTab"
widgetVar="usersTable"
tableStyleClass="data" paginator="true" rows="5"
filteredValue="#{userController.filteredUsers}"
editable="true"
rowKey="#{item}">
<p:ajax event="rowEdit" listener="#{mybean.onEdit}" update=":userForm:growl" />
<p:ajax event="rowEditCancel" listener="#{mybean.onCancel}" update=":userForm:growl" />
<f:facet name="header">
<p:outputPanel>
<h:outputText value="Search all fields:" />
<p:inputText id="globalFilter" onkeyup="('usersTable').filter()" style="width:150px" />
</p:outputPanel>
</f:facet>
<p:column sortBy="#{item.firstName}" filterBy="#{item.firstName}"
filterMatchMode="startsWith">
<p:cellEditor>
<f:facet name="header">
<h:outputText value="First Name" />
</f:facet>
<f:facet name="output">
<h:outputText value="#{item.firstName}" />
</f:facet>
<f:facet name="input">
<p:inputText value="#{item.firstName}" style="width:100%"/>
</f:facet>
</p:cellEditor>
</p:column>
<p:column sortBy="#{item.lastName}" filterBy="#{item.lastName}" filterMatchMode="startsWith">
<p:cellEditor>
<f:facet name="header">
<h:outputText value="Last Name" />
</f:facet>
<p:column headerText="Update" style="width:6%">
<p:rowEditor />
</p:column>
</p:dataTable>
My code in bean:
public String onEdit(RowEditEvent event) {
User user=(User)event.getObject());
user.getFirstName();
}
code in the bean for getting the list in ui:
public List<UserBean> getUsersList(){
List<UserBean> retval = new ArrayList<>();
for (Object[] tuple : myFacade.getUserList()) {
UserBean ub = new UserBean();
ub.setFirstName((String) tuple[0]);
ub.setLastName((String)tuple[1]);
ub.setEmailAddress((String)tuple[2]);
ub.setOfficeNumber((String)tuple[3]);
ub.setRole((String)tuple[4]);
retval.add(ub);
}
return retval;
}
I have tried the suggestions that were given in some of the posts but they did not work.Could anyone let me know how can I get the new values.I am using glassfish 4.0,primefaces 3.5.
I was able to figure out the problem..Every time when I am getting the list in the getter method I am calling the database to load the data..But this should be done only if the list is null.The following code gives you a clear picture:
public List<UserBean> getUsersList(){
if(retval == null)
{
retval = new ArrayList<>();
for (Object[] tuple : myFacade.getUserList()) {
UserBean ub = new UserBean();
ub.setFirstName((String) tuple[0]);
ub.setLastName((String)tuple[1]);
ub.setEmailAddress((String)tuple[2]);
ub.setOfficeNumber((String)tuple[3]);
ub.setRole((String)tuple[4]);
retval.add(ub);
}
}
return retval;
}
So getUsersList is my value of var in the p:datatable and now when I call the onEdit it will check for the list if it is null it does a database call or does not call the database.
