Interesting trick :). But I think it should work. Like you said in the
worst case the user will see the new data at the next refresh.

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?

Hi Denis,

The current update mechanism in the inspector is very light, in the sense
that it only updates the visual representation of elements and does not
recompute them, nor offers any hooks into the update process.
Indeed having a way to also recompute the display elements could be useful.
We could change the update mechanism to add different kind of update
strategies.

Cheers,
Andrei
