jsf 2 - this.jq.draggable is not a function when using primefaces dialog framework -

-

i'm trying open dialog using primefaces dialog framework in:

http://www.primefaces.org/showcase/ui/df/basic.xhtml

my jsf code:

<p:commandbutton icon="ui-icon-extlink" actionlistener="#{grabacionesservicios.vergrabacion}"></p:commandbutton>

in grabacionesservicios managed bean following method:

public void vergrabacion() {     requestcontext.getcurrentinstance().opendialog("dialog_playgrabacion"); }

amd dialog_playgrabacion.xhtml simple helloworld jsf page.

when click button opening dialog dialog_playgrabacion.xhtml contents next javascript error:

uncaught typeerror: this.jq.draggable not function

in primefaces.js file.

i have read other post , found solution talk inserting following code in head section:

<h:outputscript library="primefaces" name="jquery/jquery-plugins.js"/>

i have paste code in different locations same error.

when use developer tools in chrome , consult network activity see how jquery-plugins.js correctly downloaded seems downloaded after primefaces.js. perhaps error? how can force file downloaded before primefaces.js

can me please?

thanks!

my faces-config.xml:
