[Pharo-project] Nested progress bars

[Martin Dias]

Hi all.

Given the next code, could you explain me why nested progress bars are
not handled by my #on:do:?
How can I achieve that?

[
'main task'
        displayProgressFrom: 0 to: 5
        during: [ :bar |
                0 to: 5 do: [:x | bar value: x.
                (Delay forMilliseconds: 200) wait.
                
                'nested task ' , x printString
                        displayProgressFrom: 5 to: 10
                        during: [ :bar2 |
                                5 to: 10 do: [:x2 | bar2 value: x2.
                                (Delay forMilliseconds: 200) wait] ] ] ]

]       on: ProgressInitiationException
        do: [ :ex |
                ex sendNotificationsTo: [ :min :max :curr |
                        self traceCr: curr ] ].


Thanks in advance.
