    <p>I'm starting to use JSF with primefaces library over an Hibernate project. I've tried to use wizard component to manage a form but, when I click any of the buttons in the wizard, I get the following warning and the action listener is not invoked. </p> <p>I think the problem is that, in the wizard there are some p:commandButton because when I use h:commandButton, everything works. Could someine explain in what way primefaces commandButton ih different from the standard one, and how could I face this problem? What's different in the rendering process? </p> <p>Thanks for your help! Here's the warning:</p> <pre><code>9-ott-2012 9.50.43 org.apache.myfaces.trinidadinternal.context.PartialViewContextImpl getPartialResponseWriter AVVERTENZA: getPartialResponseWriter() called during render_reponse.

    1. COtry changing `save(ActionEvent actionEvent)` into `save()` , also you better use annotations instead of `faces-config`

    3. COI tried all of this combination. The problem is that whit a standard h:commandButton, it works! Maybe I have not understood something about the Ajax behaviour of the p:commandButton. Either the flowListener="#{traduttoreBean.onFlowProcess}", that is called when Next button is pressed, doesn't work!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
