Actually I found trick:

composite fastTable

title: 'Devices';
display: [ devices ];
wantsAutomaticRefresh: true;

     *when: GLMPresentationRefreshRequest do: [myModel update].*

Event handler can be executed after actual view update because announcer do
not ensure delivering order. But in that case new value will be shown at
next refresh which should be fine.
What you thing?
