MAToOneRelationDescription dispaly data

Hi All,

my english language is very limited, i'm sorry.

I have a PersonModel with some descriptions.

One of it, descriptionAddress is based on MAToOneRelationDescription

with componentClass: MAExternalEditorComponent

and classes: ( Array with: MAAddressModel )

When rendering PersonModel asComponent for the descriptionAddress the system
display the relative low priotity description near the Remove and Edit buttons.

I need to dispaly more data near the button.

I have add, to the descriptionAddress definition the:

reference: ( MAAddressModel descriptionCity, MAAddressModel descriptionRegion)

but d'ont work well.

The same problem i found in MASingleOptionDescription where reference: d'ont work.

For MASingleOptionDescription i have solve with optionsAndLabels:

In the MAToManyRelationDescription the reference: define the data to display for any item.

I think same behaviour in MAToOneRelationDescription and MASingleOptionDescription but i wrong. ?!

My question now is:

how i can display some data near the Remove / Edit buttons relative to the MAAddressModel instance.

Cheers,

Dario

This means you want a different string to be displayed?

If so, try this

reference: (MAContainer with: (MAStringDescription new
selectorAccessor: #printString; yourself))

and implement your own printOn: method in your referenced object as
you wish.

Cheers,
Lukas

I've test this solution but d'ont work.

The printOn: method in my referenced object is never call.

I work with vw7.5 and seaside 2.8a1.

This is odd, because it works on Squeak.

Actually in Squeak you don't even need to specify any reference
description, because the default is an MAStringDescription what causes
#asString to be sent to the object.

Since you are on VisualWorks #asString might not work as expected.
Maybe you want to try and implement it yourself on your object and
don't specify any reference description?

I added a test in Squeak that should find that kind of bug.

Re: MAToOneRelationDescription dispaly data

Mhh, I just noticed that there is a possible bug in
MAExternalEditorComponent related to printing one-to-one relations.
This is ready to review in Magritte-Seaside-lr.261.
