jsf - primefaces reload galleria -

-

reference: http://www.primefaces.org/showcase/ui/galleria.jsf

my page:

<p:galleria id="merchant-gallery" value="#{testcontroller.imageids}" var="item" autoplay="false" >       <p:graphicimage width="300" value="#{imagestreamer.image}" >         <f:param name="id" value="#{item}" />     </p:graphicimage> </p:galleria>

i tried enclosing <p:galleria> in form , added <p:remotecommand name="updateme" update="@form"/> after calling updateme make galleria blank.

*update

testcontroller bean:

public list<integer> getimageids() {     int aid = (integer) facescontext.getcurrentinstance().getexternalcontext().getsessionmap().get("user_id");     entitymanagerfactory emf = persistence.createentitymanagerfactory("test2pu");     entitymanager em = emf.createentitymanager();     typedquery<merchant> tp = em.createquery("select account a.id = :id", account.class);     tp.setparameter("id", aid);     current = tp.getsingleresult();      collection rawphotocollection = current.getphotocollection();      imageids = new arraylist<integer>(rawphotocollection);     list<photo> photolist = new arraylist<photo>(rawphotocollection);      (int = 0; < photolist.size(); i++) {         int imageid = photolist.get(i).getid();         imageids.set(i, imageid);     }      return imageids; }

imagestreamer bean:

@ejb private test.controller.photo.photofacade ejbfacade;  public streamedcontent getimage() throws ioexception {     facescontext context = facescontext.getcurrentinstance();      if (context.getcurrentphaseid() == phaseid.render_response) {         return new defaultstreamedcontent();     } else {         map<string, string> param = facescontext.getcurrentinstance().getexternalcontext().getrequestparametermap();         string id = param.get("id");          photo image = ejbfacade.find(integer.valueof(id));         return new defaultstreamedcontent(new bytearrayinputstream(image.getimage()));     } }

i reworked example , have same issue. not related upload or remotecommand. think bug in primefaces. see http://code.google.com/p/primefaces/issues/detail?id=4840 similar issue. when command 

primefaces.cw('galleria','widget_companydetail_merchant-gallery',{id:'companydetail:merchant-gallery',transitioninterval:0,panelwidth:640,panelheight:480,custom:false},'galleria');

in firebug console, galleria reappears. when changing remotecommand , adding javascript oncomplete works. 

<p:remotecommand name="updateme" update="@form" oncomplete="primefaces.cw('galleria','widget_companydetail_merchant-gallery',{id:'companydetail:merchant-gallery',transitioninterval:0,panelwidth:640,panelheight:480,custom:false},'galleria');"/>
