yes... I also can use
presenter morph
instead
presenter magritte
but I think glamour deserves a better way, IMHO... as Doru said, this is a very common
pattern, so it should be an easy way to perform it...
cheers,
Esteban

One trick that I do in AspectMaps to notify updates (going around glamour limitations) is
to use announcements. For example I send an event whenever the underlying model has
changed:
self announcer announce: (AMModelChanged new).
I force a refresh of the pane when this happens using the code below. You could do the
same: send an event when the #save call is made ...
browser transmit
to: #mpanel;
from: ... ;
andShow: [:a | a mondrian
painting: [ ...];
updateOn: AMModelChanged from: [:ent | self announcer ]].

Hi,
I'm making some progress here... but now I need another feature.
As I'm using glamour and magritte to present some data who is persistent, I need to
being able to react to a #save call on a magritte presentation.
For instance... in my browser:
...
browser transmit
to: #detail;
from: #list;
andShow: [ :presenter |
presenter magritte
title: [ :anItem | anItem asString ];
act: [ :presentation :anItem | self removeItem: anItem ]
icon: LWUIIcons / #userTrash
entitled: 'Borrar' ].
...
how can I know if user pressed #save and there is a modified object there? (to update
persistent repository)
working with plain magritte, I'd do:
...
anObject asMorph
onAnswer: [ :value | blah, blah ];
morph.
...
...so... is there a way in glamour to react to updated objects?
cheers,
Esteban
