The ID of a field to monitor for changes. If a change occurs in the monitored field the select box will refresh.
The ID of any field on the current page capable of generating "change" events. That means any text input fields, or select elements (dropdown lists or list boxes). If updateWamName and updateWrName have been specified, the weblet will call the webroutine to request a fresh copy of the [listname] working list. Otherwise it will re-apply the selectorValue filter to the list it already has and rebuild the select list from that.
