Hi,

i work with squeak update to the last 2.9 seaside and Magritte-All-lr-269.

I have a class 'MAArticoloModel ' defined with some descriptions.

One description is based on MAFileDescription

descriptionPicture

^ ( MAFileDescription new)

autoAccessor: 'immagine';

beRequired;
label: 'Immagine';

priority: 60;

yourself

Now when update an item with :

self call: ( anMAArticoloModel asComponent) readonly: false;

addValidateForm;

addMessage: 'Update item;

yourself

all work fine.

But when display an item with:

self call: ( anMAArticoloModel asComponent) readonly:true;

addForm: #(cancel);

addMessage: 'Display item';

yourself

i found the error: MessageNotUnderstood: WAMimeType >> copyUpTo.

Any pointers would be greatly appreciated!

Thanks!

Dario
