    <p>To the point, you'd like to retain the property responsible for the <code>rendered</code> condition in the subsequent request. There are several solutions for this problem:</p> <ol> <li><p>Put bean in session scope. It's easy, but it hurts. It's bad for user experience since changes will be reflected in all tabs/windows the user has open in the same session.</p></li> <li><p>Use <code>&lt;h:inputHidden&gt;</code> to transfer the property. In theory easy, but in practice it hurts as well. The value will namely get lost whenever a validation/conversion error has occurred in any of other inputs in the same form. This is an odditity in how JSF handles hidden input elements. A workaround is to use <code>&lt;h:inputHidden binding="#{bean.hidden}"&gt;</code> and do a <code>hidden.getValue()</code> and <code>hidden.setValue()</code> in bean.</p></li> <li><p>If you're using <code>&lt;h:commandLink&gt;</code> instead of <code>&lt;h:commandButton&gt;</code>, then you can use <code>&lt;f:param&gt;</code> to transfer the property. It will be available as request parameter, you can check for it in bean's (post)constructor.</p></li> <li><p>Use <a href="http://myfaces.apache.org/tomahawk/" rel="nofollow noreferrer">Tomahawk's</a> <a href="http://myfaces.apache.org/tomahawk-project/tomahawk/tagdoc/t_saveState.html" rel="nofollow noreferrer"><code>&lt;t:saveState&gt;</code></a>. The perfect solution as far. This will retain the value (or even a complete bean) in the subsequent request.</p></li> </ol> <p>If you're already on JSF 2.0, the <a href="http://balusc.blogspot.com/2010/06/benefits-and-pitfalls-of-viewscoped.html" rel="nofollow noreferrer"><code>@ViewScoped</code></a> would have solved this all. It behaves like the <code>&lt;t:saveState&gt;</code>.</p> <h3>See also:</h3> <ul> <li><a href="https://stackoverflow.com/questions/2118656/hcommandlink-hcommandbutton-is-not-being-invoked">commandButton/commandLink/ajax action/listener method not invoked or input value not updated</a></li> </ul>

    1. CO<Quote>you'd like to retain the property responsible for the rendered condition in the subsequent request.<Quote> What I dont understand is - The Command button is displayed because the rendered was true. What is meant by retaining the property here? Is not it already retained when the Button is clicked ? (!)

    2. COA request scoped bean is garbaged when the HTTP response is finished. A fresh new bean will be created when you fire a new HTTP request by clicking link/button. This fresh new bean will have all default properties. The default property might have caused the `rendered` attribute to evaluate `false` during restore view. You have to take care that the bean get recreated with the same properties as it was during displaying the form. You can make use of the bean's constructor, `@PostConstruct` method, component binding, `t:saveState`, etc for this.

    3. COThanks BalusC.I get what you say. But I do not know how to do this. I cannot use Tomahawk lib files. How do I do this either using component binding or using the bean's constructor? Do you have sample code?

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.
