Body
Question was asked more than a year ago, but here are some code snippets that hopefully will help someone else in the future: <pre><code> <h:panelGrid> <p:progressBar widgetVar="progressBar" ajax="true" value="#{archiveCopyCreator.progress}" interval="1000" labelTemplate="{value}%" styleClass="animated" style="width: 500px;"> <p:ajax event="complete" listener="#{archiveCopyCreator.onComplete}"/> </p:progressBar> <h:panelGrid styleClass="centered"> <p:commandButton value="Avbryt" action="cancel" ajax="false" immediate="true" /> </h:panelGrid> </h:panelGrid> <script type="text/javascript"> $(document).ready(function() { progressBar.start(); }); </script> </code></pre> I create a progressBar, and update it based on a value in one of my beans. When complete, a ajax call is made to the bean. The progressbar is started manually using javascript. <pre><code>@Component public class ArchiveCopyCreator implements Serializable { private static final long serialVersionUID = 1L; protected Integer progress; public Integer getProgress() { if (this.progress == null) { this.progress = 0; } else { this.progress = this.progress + (int) (Math.random() * 15); if (this.progress > 100) { this.progress = 100; } } return this.progress; } public void setProgress(final Integer progress) { this.progress = progress; } public void cancel() { this.progress = null; } public void reset() { this.progress = null; } public boolean hasProgress() { return this.progress != null; } public void onComplete() { RequestControlContext requestContext = (RequestControlContext) RequestContextHolder.getRequestContext(); this.objektidentiteter = null; this.progress = null; requestContext.handleEvent(new Event(this, "complete")); return; } </code></pre> } Actual progress is faked using Math.random in this example. Note that onComplete() is called using ajax from progressBar. That javacode does a transition to my next Spring Webflow state with the id "complete". Remember to create a new backing bean for each user/flow... ArchiveCopyCreator in my example is a @Component since i want to share it between flows and users.

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.
