Until now we were using Spring Webflow 2.3, which brought the "sf" namespace and Spring.js, which could be used to display view-states in a popup.
Webflow 2.4 deprecated Spring.js and removed the taglib with the following statement:
Previous releases of Spring Web Flow shipped with a component library which provided Ajax and client-side validation capabilities for JSF 1.2 environments. Applications using these components will need to switch to a 3rd party JSF component library such as PrimeFaces or RichFaces.
Now i have added a dependency to Primefaces 5.2 to my pom.xml and everything seems to work fine, except for SWF Popups, which simply redirect to the new view-state.
First page:
<ui:composition template="#{templatePath}"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:p="http://primefaces.org/ui">
<ui:define name="content">
<h:form id="formDashboard">
<p:commandButton id="addWidget" value="Hinzufügen" action="add-widget"/>
</h:form>
</ui:define>
</ui:composition>
Second page (should be rendered in a popup):
<ui:composition
xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.org/ui">
<ui:fragment id="popupFragment">
abc
</ui:fragment>
</ui:composition>
Flow definition:
<flow xmlns="http://www.springframework.org/schema/webflow"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/webflow http://www.springframework.org/schema/webflow/spring-webflow.xsd">
<view-state id="start" view="dashboard.xhtml">
<transition on="add-widget" to="popup-addWidget"/>
</view-state>
<view-state id="popup-addWidget" view="popup-addWidget.xhtml" popup="true">
<on-render>
<render fragments="popupFragment"/>
</on-render>
</view-state>
</flow>
Spring configuration:
<bean class="org.springframework.faces.webflow.JsfFlowHandlerAdapter">
<property name="flowExecutor" ref="flowExecutor"/>
</bean>
<bean class="org.springframework.webflow.mvc.servlet.FlowHandlerMapping">
<property name="flowRegistry" ref="flowRegistry"/>
</bean>
<webflow:flow-executor id="flowExecutor" flow-registry="flowRegistry">
<webflow:flow-execution-listeners>
<webflow:listener ref="facesContextListener"/>
</webflow:flow-execution-listeners>
</webflow:flow-executor>
<webflow:flow-registry id="flowRegistry" flow-builder-services="flowBuilderServices"/>
<!-- Populates the flowRegistry on startup. Removing this and manually adding all flows changes nothing. -->
<bean class="config.FlowRegisteringBeanPostProcessor"/>
<faces:flow-builder-services id="flowBuilderServices"/>
<faces:resources/>
<bean id="facesContextListener" class="org.springframework.faces.webflow.FlowFacesContextLifecycleListener"/>
I'm not including the web.xml, since there is nothing special.
Using Mojarra 2.2, Primefaces 5.2, Spring 4.2 and Webflow 2.4.1.
Using Firebug i can see that the server POST response issues to redirect, which JSF/Primefaces honors and does a full redirect to the new view-state instead of showing a popup:
<?xml version='1.0' encoding='UTF-8'?>
<partial-response id="j_id1"><redirect url="/Demo/spr/dashboard?execution=e1s2"></redirect></partial-response>
If anybody managed to get popup="true" working with these versions, with or without Spring.js, i'd be happy to hear about it.
We ended up using Primefaces' p:dialog and p:confirmDialog, instead of Webflow popups.
This doesn't really answer my question, but i can't see an answer to this seeing that Webflow sends the same response no matter if popup is set to true or false.
