Can an @Observer force an AJAX reRender?

[skidvd.seamframework.abilsoft.com]

Can an @Observer of a Seam Component Driven Event force an Ajax4JSF reRender?  If so, are there any examples anyone can point me to?

TIA!

You would need to use some form of ajax push to get an event from the business logic to the view layer

Like a4j:push (it seems to be the tool for the job)?

Has anyone tried combining @Observer with a4j:push ?

how bout @RaiseEvent with @Observer with a4j:push?

how bout the scenario where a user logs out and you @RaiseEvent that a user has logged out in your backing bean and then use @Observer to a4j:push to all other current users of the app that user foo has logged out (as a rich:modalPanel).

can you do that in a Seam app?  most likely would involve Application scoped component(s).

typically we concentrate on one session/client at a time (unless it's a workflow/BPM scenario).

anybody tried this before with Seam?

I can't say for a4j, but it works great with ICEfaces.
