Because we are going over all the weak on:do: and rewriting the ones we can.
whenListChanged: aBlock
"Specify a block to value after the contents of the list has changed"
"Basically when you set a new list of items"
<api: #event>
| block |
block := [ :announcement :ann |
aBlock
cull: announcement newContents
cull: announcement oldContents
cull: announcement
cull: ann ].
listAnnouncer weak
on: ValueChanged
do: block
