p:autoComplete - Pass More parameters

I'm using JSF 2.2 with PrimeFaces 5.3 and I'm trying to work with the p:autoComplete

I think I'm doing some kind of syntax error, but I'm not able to find it

I've this piece of page

<h:selectOneMenu id="countryDropdown" value="#{myController.selectedCountryId}">
   <f:selectItems value="#{myController.countries}" var="co" itemValue="#{co.id}" itemLabel="#{msg[co.name]}"/>
</h:selectOneMenu>

<p:autoComplete 
   dropdown="true" 
   value="#{myController.selectedAutocompleteId}" 
   completeMethod="#{myController.callMyAutocompleteMethod}">
      <f:attribute name="selectedCountryId"  value="#{carCountryDropdown}" />
</p:autoComplete>

In order to perform the auto-completion task I need the value of the "countryDropdown" also. Which syntax I need to use in order to retrieve inside the auto-completion method the value of the "countryDropdown" select item?

Inside the auto-completion method I can use the following code

UIComponent.getCurrentComponent(context).getAttributes().get("selectedCountryId");

but I get always null.

Can you help me?

You can use ajax, < p:selectOneMenu> supports change event:

< p:selectOneMenu ..>
    < p:ajax event="change" listener="#{myController.subjectSelectionChanged}" />
    <!--...-->
< /p:selectOneMenu>

which triggers listener subjectSelectionChanged in which you can return the value of the "countryDropdown" in carCountryDropdown
