Hmmm, yeah, that's interesting. Maybe others thought of this before,

the linked component was removed/ replaced, right?

Right, my first instinct was to ask for an onRemove as part of the component/behavior lifecycle. But with larger issues looming for wicket, I decided to hold off. Turns out my problem with the AjaxTimer was pretty straight forward to solve since wicket generates unique ids for all components even if they occupy the same place in the hierarchy.

In case anyone is interested, you just need to override getCallbackScript :

 @Override
            protected CharSequence getCallbackScript(boolean recordPageVersion)
            {
                String mId = getComponent().getMarkupId();
                StringBuilder sb = new StringBuilder("exec_func(function() { ");
                sb.append("var el = wicketGet('" + mId + "'); ");
                sb.append("if(null != el) {");
                sb.append(super.getCallbackScript(recordPageVersion));
                sb.append("}");
                sb.append("})");
               
                return sb.toString ();
            }
