Dear all,
I am starting to really use JSF 2.2. I am trying to use Faces Flows. I
am starting with a very simple flow, whose name is "flow1".
So, under src/main/webapp, I have a flow1 directory containing
flow1-flow.xml
flow1.xhtml
flow1b.xhtml
flow1-flow.xml contains :
<?xml version="1.0" encoding="UTF-8"?>
<faces-config
xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
xmlns='http://xmlns.jcp.org/xml/ns/javaee'
xsi:schemaLocation='http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd'
version='2.2' >
<flow-definition id="flow1">
<flow-return id="returnFromFlow1">
<from-outcome>/accueil</from-outcome>
</flow-return>
</flow-definition>
</faces-config>
With such a simple config, using conventions would be a better choice
than configuration, but I plan to add more things to it... :-)
I use a @FlowScoped bean declared this way :
@Named
@FlowScoped("flow1")
public class MinintFileContext implements Serializable {
....
}
and it does not work. I have the following exception :
javax.servlet.ServletException: javax.servlet.ServletException:
javax.el.ELException:
javax.enterprise.context.ContextNotActiveException: WebBeans context
with scope type annotation @FlowScoped does not exist within current thread
To make it work, I have to use @ManagedBean instead of @Named.
My first question is : I do not understand why... In my (obviously
wrong) understanding, @Named was a super-set of CDI-managed beans,
including @ManagedBean-s.
Another question...
I am using PrimeFaces p:menubar . I noticed that I can not use "/flow1"
as the outcome of a menuitem
Ex : <p:menuitem value="Blah blah blah" outcome="/flow1" />
I have to use
<p:menuitem value="Blah blah blah" outcome="/flow1/flow1" />
Why ? This might be a PF-specific question.
Finally, I am failing to use the flow-return configuration.
I tried
<p:commandButton value="Terminer" action="returnFromFlow1"/>
and
<h:commandButton value="Terminer" action="returnFromFlow1"/>
But it just does not work.
So, I tried to change the config to
<flow-return id="returnFromFlow1">
<from-outcome>#{minintFileContext.returnValue}</from-outcome>
</flow-return>
and added a
public String getReturnValue() {
return "/accueil";
}
method to he MinintFileContext bean, but it does not work better.
Any idea ?
Thanks in advance

remove in-house dependencies from the following tree) :
