I have uploaded Glamour-Examples-BenComan.232 & 233 adding ability to

using updateOn:from: I now have a bit of an understanding about
Announcements, so I am thinking about how to remove the 'browser update'
shown above. I see three possible approaches which I am unsure which
are suitable or not...
1. Using the Magritte Presentation for the List Presentaiton's
updateOn:from: - but I don't know what announcement it might listen for.
2. Create a new announcer in a temporary variable in the
'magritte' method and somehow pass to both List Presentation and
Magritte Presentation for them to operate on.
3. Use Glamour inner/outer transmission from the Magritte
Presentation to the List Presentation - but I haven't worked out how to
do this.
Your thoughts would be appreciated.

There was no reply, but there will be one now :)
Your solution should work, but it is sub-optimal and it is a
conceptual hack because you are refreshing the entire browser in order
for the contents of the Magritte presentation to refresh. You could
probably still just update the Magritte presentation, but this
behavior should be provided directly by the logic of the presentation.
Could you give it a try to add this code in the renderer?
Cheers,
Doru
GLMBasicExamples>>magritte requires not only the update of the Magritte
presentation in the right-hand-pane. The List in the left-hand-pane also needs
to update when the associated value is modified in the Magritte pane. For a
more optimal solution I am assuming I need to understand "outer" ports or
Announcements better - but I'm not there yet. I'd love to do more but
(common complaint) it is a distraction from what I am trying to do for my
masters project and time for that is running out. I'd love it if someone could
demonstrate the preferred way by modifying the example, so that I can do it
right in my project, but the "whole-browser" hack will do, for me, for now.
I did get it working for the Magritte-pane-only using 'self update' in
GLMMagrittePresentation>>reactOnAnswerFor:
which I have now uploaded as Glamour-Magritte-Presentations-BenComan.3
