MAMultipleOptionDescription options from instance

Hi everyone,

I've just got started with Magritte and have a couple of new-bee questions.

1. I have a MAMultipleOptionDescription and the options come from sending #availableOptions to the current instance. I can't see how i would do this with #asDynamicObject

2. I have a SingleOptionDescription with a dynamic options object - can i provide a display block or how would i control what is displayed in the popup. I found an optionsAndLables but it doesn't take a dynamic object.

Does anyone know how to achieve this, or can point me to the appropriate documentation. Sorry for the simple questions.

Thanks in advance,

Phil

MAMultipleOptionDescription is the same as MASingleOptionDescription
as far as retrieving the options concern.

I do not suggest to use #asDyanmicObject. I suggest that you override
#description on the instance side of your object and use
#optionsAndLabels: to set the possible options

Cheers,

The Magritte-Scriptaculous package adds this kind of functionality, here
is a description from my image, in which the accessor has an alternate
accesor that is used to obtain the list of options.

descriptionImprintChooser
^MASingleOptionDescription new
accessor: ((#imprint asAccessor) visible: #hasImprint; options:
#imprintOptions; tooltip: #imprintInfo);
propertyAt: #labelSelector put: #chooserLabel;
reference: WSUserImprint new;
label: 'Imprint';
beRequired;
bePersistOnChange;
priority: 140;
