Hi Chrisi, I'm a beginner too, so I'll try to share what I just understood :)

You have more than a way to go.. but you should at first, create a navigation rule for page1.faces in your faces-config.xml:

<navigation-rule>
    <from-view-id>/page2.jsp</from-view-id>
    <navigation-case>
        <from-outcome>gotoPage1</from-outcome>
        <to-view-id>/page1.jsp</to-view-id>
    </navigation-case>
</navigation-rule>


1) With a field

If you have a field in your page2.faces binded to #{controller.name }, things are very simple. Simply put a

<h:commandLink value="Goto page 1" action="" />

in page2.jsp. You fill find the property already updated to the field value after you got forwarded to page1.faces.


2) Without a field, and without using a controller method

If you want to "manually" set the property value from the jsp page, without a field, you can do like this in your page2.faces :

<h:commandLink value="Goto page 1" action="">    <t:updateActionListener property="#{controller.name}" value="Chrisi" />
</h:commandLink>

The t:updateActionListener tomahawk component will update the controller property to the specified value before bringing you to page1.faces.


3) Using a controller method

Lastly, you can also create a method in your controller bean to perform the job:

public void updateAndGo() {
    setName("Chrisi");
    return "gotoPage1";
}

This could be good if you need more complex processing. To invoke it, you have to put in your page2.faces something like:

<h:commandLink action="" />


Hope this help

Hello,

 

this is a beginner question:

 

I have two java server faces pages.

 

Nr.1  'page1.faces':    Contains just a simple form with an input-field like the following

<h:inputText value="#{controller.name}"/

 

Nr.2 'page2.faces':   Should contain a simple link to 'page1.faces'.  When clicking on

the link, a value like 'Chrisi' should be transfert to the text-field and page1.faces should

be rendered.

 

What is the JSF way to do this right?

Sure, I can do something like this <a href="" and

let the page1.faces check the parameter 'name' using EL.

But there should be a better way using the JSF lifecycle and the controller/modell concept, right?
