Comment #21 on issue 492 by esteba...@gmail.com: Glamour browsers do not release all subscriptions to announcer objects http://code.google.com/p/moose-technology/issues/detail?id=492
looks like adding a #makeWeak send to GLMUpdateAction>>#registerInPresentation makes the bahavior better (I don't know if it corrects the problem, but it reduces the announcement subscription propagation a lot).
GLMUpdateAction>>#registerInPresentation self announcerObjects do: [: announcerObject | announcerObject notNil ifTrue: [ (announcerObject on: self announcement send: #actOn: to: self) makeWeak. "we remember the announcer object to be able to unregister from it when the presentation goes away" self presentation registeredAnnouncers add: announcerObject ] ]
