I have a JSF page with a few fields. I followed this tutorial from BalusC and all is good. I then added RichFaces support to it, which is working fine. I can see popups etc working.
Now what I am trying to do is that once a person has been registered, I want to show the name in the popup (this is also fine I can see that in the popup). Then I want to be able to change that name inside the popup and have that reflected in the parent, but I have no clue how to do that. Please have a look.

Just move the
rich:popupPanelout of the main form, and give it it’s own form. If you then submit the form that’s in the dialog, the entire page will re-render.Since the backing bean is view scoped, the previously user data will be retained and only the user name will be updated with whatever you entered in the dialog.
Additionally, you can submit the form via AJAX, give the main form an ID and re-render that.
E.g.
I used the A4J
commandButtonhere which has a convenientoncompleteattribute. You can do a similar thing with theoneventattribute on the standard ajax tag, but using slightly more code.Do note that if the main form has validation errors, it’s without any counter measures impossible to update from the other form (if you run into that, you’d best open a new question for that particular situation).
