I'm having some problem getting a repeater with a nested repeater update with ajaxmanger.

Se example page here: http://dev12.spireweb.no/repeater_ajax.aspx 

I just want the nested repeater in the post to update when a comment this added or deleted. This only works for the first post.
Is there a way to solved this issue?

Hi Kari,

Could you please try to set ClientIDMode for the page where the repeater controls is placed to "AutoID"  and verify if this makes any difference?
