select a record from a p:datatable using a p:remoteCommand

  • 772

I have one p:datatablewith n records, among these a field with a p:inputText, when you double click on it, it calls a p:remoteCommandthat executes a method of a managedBean.

The problem is that in the method I extract the record from where the event originated, but it does not bring me the correct record, it always brings me the last record, please someone help me.

Attached code:

        <p:column style="width:40px;padding-left:1px;text-align:center;">
            <f:facet name="header">
                <h:outputText value="Id Orden" />
            </f:facet>
            <p:remoteCommand name="commandDobleClicOrdenrepId" action="#{ordenTrabajoController.dobleClicOrdenrepId}" partialSubmit="true" />                       
            <h:inputText value="#{item.pk.ordenrepId}" ondblclick="commandDobleClicOrdenrepId();" readonly="true" style="border:0;background-color: #fff" 
                title="Dar doble clic desea ver la pre-factura actual."/>                                           
        </p:column>

ManagedBean

public String dobleClicOrdenrepId(){        
        SeOrdenRep seOrdenRep = (SeOrdenRep) getListadoOrdenes().getRowData();//AQUI ME DA SIEMPRE EL ULTIMO REGISTRO       
        return "form.jsf";  

    }

    Part by part:

    • p:remoteCommandall it does is define a JavaScript function that calls a method on the server. The information of which row is selected, which button calls the JS, etc. it just doesn't ship.

    • Since p:remoteCommandit defines a JS function, by putting it inside the datatableonly thing you do is that your code defines the same function once for each row. It is not very useful. take it out of thedatatable

    • To pass parameters to p:remoteCommand, do it like this:

      <h:inputText value="#{item.pk.ordenrepId}"
    ondblclick="commandDobleClicOrdenrepId([{name:'idEdit', value:'#{item.pk.ordenrepId}')"
    readonly="true" style="border:0;background-color: #fff" 
    title="Dar doble clic desea ver la pre-factura actual."/>

      and in the managed bean you pick it up with a@ManagedProperty

      @ManagedProperty("#{param.idEdit}")  
private String id;

    • p:remoteCommandmakes an Ajax request . That is, it will execute the code you tell it to, but it will not redirect you to another page.

    • Using "double click on a text field" to send to a different page is, to put it mildly, very unintuitive. Use an commandLinkor commandButton, that's what they are for and that all users will be able to identify at first.
