jsf 2 - How to get parametrs to BackingBean from jsf page in <ui:repeat> -

my xhtml:

<ui:repeat value="#{c.voices}" var="v">      <h:form enctype="multipart/form-data">           <p:fileupload fileuploadlistener="#{addnote.handlefileupload}"             convertermessage="convertermessage"             mode="advanced"               update="messages"               sizelimit="100000"                                                              allowtypes="/(\.|\/)(gif|jpe?g|png)$/">         </p:fileupload>           <p:growl id="messages" showdetail="true"/>                                          </h:form>  </ui:repeat> 

my backingbean:

 public void handlefileupload(fileuploadevent event) {     //int v.id= here need know v.id value ui:repeater     facesmessage msg = new facesmessage("succesful", event.getfile().getfilename() + " uploaded.");     facescontext.getcurrentinstance().addmessage(null, msg); } 

c.voices list of object. every object have attribute id. need know id parametr in handelfileupload how can that?

sry english , ignorance of jsf primefaces beginner in both discipline.

i put v.id in hidden field :

your xhtml:

<ui:repeat value="#{c.voices}" var="v">     <h:form enctype="multipart/form-data">         <input type="hidden" name="vid" value="#{v.id}" />         <p:fileupload fileuploadlistener="#{addnote.handlefileupload}"             convertermessage="convertermessage"             mode="advanced"             update="messages"             sizelimit="100000"             allowtypes="/(\.|\/)(gif|jpe?g|png)$/">         </p:fileupload>         <p:growl id="messages" showdetail="true"/>     </h:form>  </ui:repeat> 

and in bean using facescontext :

your backingbean:

public void handlefileupload(fileuploadevent event) {     httpservletrequest request = (httpservletrequest)          facescontext.getcurrentinstance().getexternalcontext().getrequest();     request.getparameter("vid"); // <= here are! } 

update

as stated in comments each iteration have it's own <h:form it's own <input type="hidden" name="vid". when file uploaded handlefileupload fired data of enclosing form, vid parameter sent correct #{v.id}

update 2

as balusc commented should preferably vid parameter way :

public void handlefileupload(fileuploadevent event) {      facescontext.getcurrentinstance().getexternalcontext()         .getrequestparametermap().get("vid") // <= here are! }
