JSF 2.2: request-param in navigation-rule not found

Question

I have a faces-config.xml that contains a lot of navigation rules but I'm not able to get a redirect-param in my page.

I've searched a lot about this issue but I couldn't find any helping response.

detail.xhtml:

<p:commandLink action="#{bean.delete()}">
    <f:setPropertyActionListener target="#{bean.deletionSuccess}" value="true" />
    <p:confirm header="Confirmation" message="Are you sure?"
</p:commandLink>

faces-config.xml:

<navigation-rule>
    <from-view-id>/myDetailPage.xhtml</from-view-id>
    <navigation-case>
        <from-outcome>deletionSuccess</from-outcome>
        <to-view-id>/myOverviewPage.xhtml</to-view-id>
        <redirect/>
    </navigation-case>
</navigation-rule>

Java-Bean:

   private String deletionSuccess;

    public String delete() {
        // do something
        return "deletionSuccess";
    }
    public void setDeletionSuccess(String deletionSuccess) { this.deletionSuccess = deletionSuccess; }

    public String getDeletionSuccess() { return deletionSuccess; }

overview.xhtml:

<f:metadata>
    <f:viewParam name="deletionSuccess" value="#{bean.deletionSuccess}"/>
    <f:viewAction action="#{bean.init}"/>
</f:metadata>
...
<h:form id="mainform" class="form-horizontal overview" role="form" method="post">
    <h:panelGroup styleClass="row" rendered="#{!empty housePlantBean.deletionSuccess}">
...

What am I doing wrong? Or how can I get the redirect-param in my XHTML-page?

Thanks a lot for your help!

This won't work in such way.

First of all you need to have defined <f:viewParam> on myOverviewPage.xhtml facelet, eg:

<f:metadata>
    <f:viewParam name="deletionSuccess" value="#{bean.deletionSuccess}"/>
</f:metadata>

I suppose you had it defined.

The easies way to pass params is use <h:button> or <h:link> on myDetailPage.xhtml facelet, eg:

<h:button outcome="deletionSuccess">
    <f:param name="deletionSuccess" value="#{true}"/>
</h:button>

but there is no invocation of public String delete() method.

So if you want to have redirection and invocation of this method you should use <h:commandButton> or <h:commandLink>, eg:

<h:commandButton value="submit" action="#{bean.delete}">
    <f:setPropertyActionListener target="#{bean.deletionSuccess}" value="#{true}" />
</h:commandButton>

--- UPDATE
Please keep correct file names in navigation-rule

<navigation-rule>
    <from-view-id>/detail.xhtml</from-view-id>
    <navigation-case>
        <from-outcome>deletionSuccess</from-outcome>
        <to-view-id>/overview.xhtml</to-view-id>
        <redirect include-view-params="true"/>
    </navigation-case>
</navigation-rule>

and please add to detail.xhtml:

<p:confirmDialog global="true" showEffect="fade" >
   <p:commandButton value="Yes" type="button" styleClass="ui-confirmdialog-yes" icon="ui-icon-check"/>
   <p:commandButton value="No" type="button" styleClass="ui-confirmdialog-no" icon="ui-icon-close"/>
</p:confirmDialog>

or remove <p:confirm header="Confirmation" message="Are you sure?"/> from <p:commandLink> tag
