Question

I’m using Primefaces p:dialog with two beans in action: one is the backing bean of the original page (A) and the other bean is the one behind p:dialog (B). Both are view-scoped beans.

Is this possible to pass a callback method to B as a parameter so that B can call this method and fire some actions on A with proper parameters? Something like this:

<p:dialog ...>
    <ui:include>
         <ui:param name="callback" value="[a possible callback method]" />
    </ui:include>
</p:dialog>

Answer 1

This worked:

a.xhtml:

....

<p:dialog ...>
    <ui:include src="b.xhtml">
         <ui:param name="targetObject" value="#{bean.value}" />
    </ui:include>
</p:dialog>

Then in b.xhtml

<p:commandLink>
    <f:setPropertyActionListener target="#{targetObject}" value="#{objectInDialog}" />
</p:commandLink>

This causes a click on the commandLink in dialog a call to bean.setValue(objectInDialog)
