JSF Page Navigation: Unexpected RuntimeException

I have the following navigation rules defined in faces-config.xml. I am able to navigate to second page, however from second page to first, I am not able to navigate. What could the reason, anything wrong with navigation rules? I would like to do navigation without redirect.

JSF version is 1.1

 <navigation-rule>
        <from-view-id>/first.jspx</from-view-id>
        <navigation-case>
        <from-action>#{bean.setSelectedItem}</from-action>
            <from-outcome>form1</from-outcome>
            <to-view-id>/second.jspx</to-view-id>
        </navigation-case>
    </navigation-rule>
    <navigation-rule>
        <from-view-id>/second.jspx</from-view-id>
        <navigation-case>
            <from-action>#{bean2.testBack}</from-action>
            <from-outcome>form2</from-outcome>
            <to-view-id>/first.jspx</to-view-id>
        </navigation-case>
    </navigation-rule>

From firebug I could see the following exception

java.lang.RuntimeException: no message available

Thanks

Update 1

Code in my second.jspx to return back to first.jspx

<ice:form id="form2">     
    <ice:commandLink action="#{bean.testBack}">
        <h:outputText value="Test" />
</ice:commandLink>
</ice:form>

Code when I click the action

public String testBack() {

    try {            
        logger.info("invoked");      
        
    } catch (Exception e) {
        e.printStackTrace();
    }
 
    return "form2";
 }

Solution

  • you can try this: (I copied this from my project so please change the values ;-) )

    <navigation-rule>
        <from-view-id>/pages/registration.jspx</from-view-id>
        <navigation-case>
            <from-outcome>next</from-outcome>
            <to-view-id>/pages/registration.jspx</to-view-id>
        </navigation-case>
<navigation-rule>

    or is there any specific reason why you use this tag?

    <from-action>#{bean.setSelectedItem}</from-action>
