How do I set Managed Bean field to the value of a ui:param?

问题

I have a JSF page that is included in other JSF pages (basically a page header, with common information). This common page has its own controller and is reliant that the page which includes this common page pass it some common data.

Specifically, I am currently trying to include this common page on other pages using:

<ui:include src="commonPage.xhtml">
   <ui:param name="commonData" value="#{thisPagesController.commonData}"/>
</ui:include>   

Which should pass "commonData" to the commonPage.xhtml page and ideally set the "commonData" property on the CommonPageController class:

@ManagedProperty("#{commonData}")
CommonData commonData;

However, this is not working... the managed property is not getting set.

What is the proper way to do this?

See comment from BalusC. There is no standard for this in the JSF API spec. Use a composite or custom component instead.
