Pass parameters using insert tag

[amit sharma]

my code is

   
<ui:insert name="dropdown">
<ui:include src="DropDown.xhtml" />
 
</ui:insert>
 

I want to pass parameters to DropDown.xhtml .But not everyone will pass parameters to tag .If someone not pass the tag then it should use some default value.
Thanks

you can pass parameters like this

on page1.xhtml

<ui:include src="page2.xhtml">
<ui:param name="param1" value="one"/>
<ui:param name="param2" value="two"/>
</ui:include>

page2.xhtml

<h:commandLink action="${bean.prevPage}">
<f:param name="prev" value="#{param1}" />

</h:commandLink>

<h:commandLink action="#{bean.nextPage}">
<f:param name="next" value="#{param2}" />

</h:commandLink>

on the backing bean you can access params ..

public String nextPage() {
String nextPage = (String)
FacesContext.getCurrentInstance(). getExternalContext()
.getRequestParameterMap().get("next");
return nextPage;
}
public String prevPage() {
String prevPage = (String)
FacesContext.getCurrentInstance(). getExternalContext()
.getRequestParameterMap().get("prev");
return prevPage;
}

Thanks for your reply .
But if some users don't want any parameters i want to use some default value for that parameter.
