PrimeFaces 3.5.14 DataTable using FilterBy

Question

I'm using PrimeFaces 3.5, with a datatable that i need use a FilterBy component. In show case, it works ok: http://www.primefaces.org/showcase/ui/datatableFiltering.jsf

well, when i do my first filter, its work and it show me result, but when i do a second filter, it stop working.

See my xHTML:

                                                                                       <p:dataTable id="users" 
                                              var="user" 
                                              value="#{userMB.users}" 
                                              rowKey="#{user.id}"
                                              selection="#{userMB.userSelected}" 
                                              selectionMode="single"
                                              rows="10"
                                              paginator="true"
                                              filteredValue="#{userMB.filteredUser}"
                                              paginatorTemplate="{CurrentPageReport}  {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"

                                    >

                                    <p:column headerText="Id" >
                                        #{user.id}
                                    </p:column>

                                     <p:column headerText="Login" filterBy="#{user.login}">
                                        #{user.login}
                                    </p:column>

                                </p:dataTable>     

Observations: userMB its my managed bean, @SessionScoped users it's a List filteredUser it's a List

it's all... thank a attention :)

this is a working PF3.5 datatable dont forget to wrap it inside an

<p:dataTable id="surveyTable" var="survey" value="#{surveyBean.surveys}" widgetVar="surveysTable" 
                                     emptyMessage="Keine Umfragen zu diesem Suchbegriff vorhanden" filteredValue="#{surveyBean.filteredSurveys}"

I am new here too, but this example worked for me. I see some problems in your example.

First if you put var="user" then rowKey="#{userMB.id}" must be rowKey="#{user.id}" Same here:

As you see I removed filterValue="#{usuario.login}" as I don't used this.

In the end this should look like this:

  <p:dataTable id="users" 
  var="user" 
  value="#{userMB.users}" 
  rowKey="#{user.id}"
  selection="#{userMB.userSelected}" 
  selectionMode="single"
  rows="10"
  paginator="true"
  filteredValue="#{userMB.filteredUser}"
  paginatorTemplate="{CurrentPageReport}  {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"

  >

      <p:column headerText="Id" >
      #{user.id}
      </p:column>

      <p:column headerText="Login" sortBy="#{user.login}" filterBy="#{user.login}">
      #{user.login}
      </p:column>

  </p:dataTable>

Maybe its not problem, but I used @ViewScoped.

Hint: you can be interested in filterMatchMode="contains"

I hope I helped you.
