jsf2 template component with parameter - jsf-2

Question

I have a jsf template page. In this template i would like to use component with parameter. Actually i would like to iterate over collection. This collection should be determined by parameters from particular page. Parameter name is selectedMenu. How can i use this in my bean?
<div id="notes">
selectedMenu: #{selectedMenu}
<h:form>
<h:inputHidden value="#{notatkaController.searchForm.kategoria}">
<f:param value="#{selectedMenu}" />
</h:inputHidden>
<ui:repeat value="#{notatkaController.items}" var="item" varStatus="iter">
<f:param value="#{selectedMenu}" />
<p class="q-title"><strong><h:outputText value="#{item.ntaData}" /></strong></p>
<p class="answer"><h:outputText value="#{item.ntaDane}" escape="false" /></p>
</ui:repeat>
<span>Moje notatki</span>
<textarea>Tu wpisz treść swojej notatki</textarea>
<span>[+] dodaj notatkę</span>
</h:form>
</div>
My bean:
#ManagedBean(name = "notatkaController")
#ViewScoped
public class NotatkaController extends AbstractController<Notatka> implements Serializable {
#EJB
private pl.alfaprojekt.model.session.NotatkaFacade ejbFacade;
private NotatkaSearchForm searchForm;
public DataModel getItems() {
if (items == null)
items = getPagination().createPageDataModel();
return items;
}
public PaginationHelper getPagination() {
if (pagination == null) {
if (paginationSize == null)
paginationSize = 10;
pagination = new PaginationHelper(paginationSize) {
#Override
public int getItemsCount() {
return getFacade().countByParam(getSearchForm());
}
#Override
public DataModel createPageDataModel() {
if (rapId == null)
return new ListDataModel(getFacade().findRangeByParam(getSearchForm(), new int[]{getPageFirstItem(), getPageFirstItem() + getPageSize()}));
else {
Long uzyId = SessionUtil.getUser().getUzyId();
return new ListDataModel(convertToRaportWierszList(getFacade().findRangeByParam(getSearchForm(), new int[]{getPageFirstItem(), getPageFirstItem() + getPageSize()}), uzyId));
}
}
};
}
return pagination;
}
}

I am not sure I understood the question but the question I answer is this:
I want to dynamically display something. I want to tell it what to display when the page gets accessed.
View:
You could then use the following:
<f:event listener="#{myBean.myMethod}" type="preRenderView" />
Bean:
public void myMethod(ComponentSystemEvent event){
//your logic here
}
With parameter:
<f:metadata>
<f:event listener="#{myBean.myMethod}" type="preRenderView" id="fevent"/>
<f:attribute name="myParam" value="#{mySecondBean.param)" />
</f:metadata>
And
public void myMethod(ComponentSystemEvent event){
String id = (String) event.getComponent().getAttributes().get("myParam");
}
