    <p>Im currently testing on JSF Bean that make use of ViewScope</p> <p>I notice this behaviour.</p> <p>When having this button :</p> <pre><code>&lt;p:commandButton value="Submit Data to Server" ajax="false" update="debugPanel" /&gt; </code></pre> <p>I can see the postconstruct happens only once, and the submission triggered by this button doest trigger postconstruct, which is correct, since it's returning to the same view. </p> <p>But when i add modify my button into this :</p> <pre><code>&lt;p:commandButton value="Submit Data to Server" ajax="false" update="debugPanel" action="viewScope2.xhtml?faces-redirect=false"/&gt; </code></pre> <p>I can see that the postconstruct method gets called for every submission, which means the bean doesnt retain it's state, although it's actualy returning to the same view. I thought this is because of the redirectin, so i omitted it, and the button becomes something like this :</p> <pre><code>&lt;p:commandButton value="Submit Data to Server" ajax="false" update="debugPanel" action="viewScope2.xhtml"/&gt; </code></pre> <p>But still, the postconstruct method gets called for every submission, which is not desireable.</p> <p>Is it possible to have this idealism :</p> <blockquote> <p>No matter whether it's explicitly or implicily defined (via attribute or via return "myview.xhtml" in action method) , whether it's using redirect or not, the viewscoped bean will always retain it's state when returning to the same view.</p> </blockquote> <p>Please share your opinions !</p> <p>Thank you .....</p>

    2. CO@BalusC: No, i did not in this case. Since without explicitly stating the target view, it still works fine, which is the first case in the original post.

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.
