Command Button inside composition page in JSF

Question

I have the same problem as user1598186 has stated in his question here : p:commandButton doesn't call bean's method in an <ui:include> page

However, no solution has been given (he has removed <ui:include> tags altogether and used variables instead)

Are there any ways of using <ui:include> and still have my backing bean's method executed, when I'm calling it inside the commandButton.

Any help will be much appreciated.

Answer 1

EL 2.2 method parameters (so, #{bean.method()} instead of #{bean.method}) can be used to pass a method signature that can be used in the actionListener attribute of a commandButton. The following is an example of passing a ManagedBean property as well as passing a method signature:

Main Page

<ui:include src="/jointeam.xhtml">
  <ui:param name="propertyValue" value="#{managedBean.property1} />
  <ui:param name="method" value="#{managedBean.performAction()}" />
</ui:include>

jointeam.xhtml

...

<h:inputText value="#{propertyValue}" />

...

<p:commandButton value="Submit" actionListener="#{method}" />

You can see how powerful this is in terms of code reuse and for many instances is less verbose and easier to use than composite components.
