Hello Marcus,

if I understand this correctly, sending changed isn't enough, you need
to send changed: anAspect

a copy from my code:
MyDataset>>prüferNamen: aCollection
prüferNamen: aCollection
        prüferNamen := aCollection.
        ^ self changed: #list.

prüferNamen is the list of strings which is displayed in the
PluggableListMorph. The symbol #list is the method of the set of data
which the PLM is plugged into.

it's just:
MyDataset>>list
   ^self prüferNamen.


In general: are you aware of the project PluggableMorphsDemo.pr?
I only dealt twice with the PLM and always loaded this project to
figure out what to do. For me its very helpful, also with
PluggableButtonMorph and PluggableTextMorph.
