You aren't getting the value because you aren't posting the form. Your "newAlias" context is going to populate the link with whatever the value of newAlias is at the time the link renders. I'm not aware of a packaged solution for what you are trying to do (doesn't mean someone else isn't going to post it as soon as I send this...) I've done something like this in the past: <t:eventlink t:event="add" t:context="['__VALUE__']">Update</t:eventlink> Then manually bind the link to the zone (copy linkZone function) and instead of using the link href directly do a replace on it for the __VALUE__ Josh On Thu, Jun 30, 2011 at 8:05 AM, Tony Nelson <tnel...@starpoint.com> wrote: > By moving the textfield outside the zone, I managed to avoid the error on > zone redisplay..
