How to create cancel or park button in my Html Dialog?

Question

On what should I pay attention when I want to create a cancel or a park button in my Html Dialog?

Accepted Answer

If you want to create a cancel button or a park button in your Html Dialog, you can create commandButton in your view.

<p:commandButton actionListener="#{logic.park}" value="Park" update="form" />

This button calls an event in which you can implement an Ivy script step where you can park now the current task.

ivy.session.parkTask(ivy.task);

Now comes the tricky part. Instead of continuing the process normally, you send a redirection to the browser:

String redirectScript = "window.location.href='"+ivy.html.taskListRef()+"';";
RequestContext.getCurrentInstance().execute(redirectScript);

The event logic.parkTask should not lead to an User Dialog Exit End which would close the dialog and go on with the process. It should lead to a User Dialog Process End.

You can do the same for the cancel button, but you would call ivy.task.reset() instead of parking the task.
