Hi, I noticed that in some complex updating between panels, using an external announcer, some of the update subscriptions were not removed when the browser is closed. I debugged a little and I founded that this implementation:
GLMUpdateAction>>unregisterFromAllAnnouncements announcerObjects ifNotNil: [ announcerObjects do: [:each | each unsubscribe: self ] ]
is bugged, because if announcerObjects are not previously computed (and in some cases that's what happens), the subscription is not removed. This implementation (just using the accessor instead the direct object), solves the problem (but I don't know is it's a right fix, and it should be a fix in other place)
GLMUpdateAction>>unregisterFromAllAnnouncements self announcerObjects ifNotNil: [ :objects | objects do: [:each | each unsubscribe: self ] ]
Cheers, Esteban
