Hello Johan,
I've coded all the examples manually, changing the names to avoid
any conflict with the ProtocolBrowser "bundled" in the Pharo 5 image
(i.e. instead of "ProtocolBrowser" I've named my class as "ProtcolFlipper").
But the result is the same.
Things improve if all the "ifNil: [ text text: '' ]" get removed from
the ProtcolFlipper>>initializePresenter method.
Obviously the text pane is no more "cleaned" when deselecting an "api"
or "api-event" row.
I've tried to substitute the "ifNil: [ text text: '' ]" with "ifNil: [
text text: 'api' ] and ifNil: [ text text: 'api-events' ] , respectively
on the "api" and "event" instances, in the ProtocolBrowser >>
initializePresenter method.
In this way I found that "ifNil:" message is sent improperly, i.e. when
a "api-event" row is selected then the message "ifNil:" of the "api"
instance is triggered, and vice-versa.
In some way this is correct: when a "api-event" row is selected then
none of the "api" rows are selected...
However I'm puzzled by the fact that the behavior seems random: creating
3 instances I can get 3 different behaviors.
have you never experienced this?
Maybe I'll check again my code...
thanks,
Matteo
