Hi Roger,
Have you looked at QCMagritte - http://www.smalltalkhub.com/#!/~DiegoLont/QCMagritte

It’s like jumping in the deep end, but I learnt a lot from it.
Cheers,

Hi Jupiter,
Thanks for that. It solved the issue. Are you by chance aware of a decent sample
application that is based Magritte that I can load in a Pharo image? Or maybe even one
based on TWBS (Twitter Bootstrap) for Magritte?
Cheers,
Roger

Hi Roger,
I seem to remember the same issue with display - I can’t remember if it’s called at all.
:)
Regardless, I opted to set a reference description along the lines of:
locationsDescription
<magritteDescription>
| template |
template := GeoLocation new.
^ MAToManyRelationDescription new
accessor: #’geoLocations';
classes: { GeoLocation };
label: ‘Locations';
reference: template descriptionDisplayString asContainer;
yourself
…and the descriptionDisplayString would be something like:
descriptionDisplayString
"<magritteDescription> note the comment to stop this becoming part of the
default description"
^ MAStringDescription new
accessor: #’printString';
label: ‘Location';
priority: 100;
beReadonly;
yourself
Let me know how it goes.
Cheers,
J

implements a #display: method which either accepts a symbol or a block to customize the
display. I've implemented a #printString method with GeoLocation and passed that to
the relation description as:
