Bean's method that returns to the previous page

Question

After performing the appropriate action, the method of my bean must ensure that the browser back to the previous page. How can I handle it?

I am using the CDI Conversation.

Enter data into the database and display it on the previous page — BillB, Feb 19 '15 at 22:24
This is the solution that I already had. I was looking for how to do the operation as back in the browser. Thank you — BillB, Feb 20 '15 at 01:33

Pass the current URI as request parameter along during navigation to the page containing that action.

<h:link value="Go to page containing that action" outcome="pageContainingThatAction.xhtml">
    <f:param name="from" value="#{request.requestURI}" />
</h:link>

(use #{view.viewId} instead if you want to pass the view ID)

Set and remember that parameter representing the URI in the view/conversation scoped managed bean.

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

Finally redirect to that URI in that action method.

public void thatActionMethod() throws IOException {
    // ...

    externalContext.redirect(from);
}

After asking you a couple of question in comments, I think what you want to do is :

On your button, specify the attribute action to a function in your bean that return a String.
The String returned need to be the navigation path to the page you want to be redirected.
If the validation is wrong on button click, then simply return null and it will stay on same page.
Make sure you define the proper navigation rule in faces-config.xml

See this tutorial for how to configure navigation rules.

See Primefaces commandButton doc for info on action tag.
