I just added a utility in AjaxUtils,
boolean isAjaxComponent(IRequestCycle cycle, String compId)
If you do boolean ajax = AjaxUtils.isAjaxComponent(cycle, thisId)
instead of
boolean ajax = AjaxUtils.isAjaxCycle(cycle)
it should do the trick. BTW, I'm not committing this small change
'cause i'm too lazy right now to setup a test page for it :)

Ahh, I see. You have recursive idBean-s ! Yes, I think you are correct, in
that case div-s should be emitted, if it's not the outer most idBean. Thanks
for figuring out, for us, and for you :) I will check in, when I will have
time
