I have a p:datatable with n records, among these a field with a p:inputText , when you double click on it, call a p:remoteCommand that executes a method of managedBean .

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

Deputy 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";  

    }

By parts:

p:remoteCommand all it does is define a JavaScript function that invokes a method on the server. The information on which row is selected, which button calls the JS, etc. it just does not ship.
Since p:remoteCommand defines a JS function, putting it within the datatable all you do is that your code defines the same function once for each row. It is not very useful. Get it out of datatable

To pass parameters to p:remoteCommand , it is done 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:remoteCommand makes a Ajax request. That is, it will execute the code you say 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 a commandLink or commandButton , that's what they are for and that all users will be able to identify the first one.
