Use Magritte to define object web interface into OODB

Hi,

i work with visualworks 7.5 / Squeak 3.9-7067\gemtools-7067dev07.10.1

and Gemstone OODB 2.2.4.

I'm interested do create web interface to some object into Gemstone ( GLASS Framework )

I think to do it with Magritte ( it's a right solution ? ).

For any object create the specific descriptionA.... , descriptionB..., ecc. ecc. class methods and use asComponent to open web interface.

I port Magritte tutorial into Glass and work fine.

But, for example, i'm interested to create Title options from other TitleInstances , ( not from Array of string, but from Array of TitleInstance )

and save in MAPersonModel title the link to one specific titleInstance

descriptionTitle
^ MASingleOptionDescription new
  options: #( 'Mr.' 'Mrs.' 'Ms.' 'Miss.' );
  autoAccessor: 'title';
  label: 'Title';
  priority: 10;
  yourself

descriptionTitle
^ MASingleOptionDescription new
  options: TitleDatabase asArrayOfInstances;
  autoAccessor: 'title';
  label: 'Title';
  priority: 10;
  yourself

Questio A)
What i need to define to do it ?

I 'can find example relative to Magritte in Gemstone?

Question B)

When change the description about one class what do i do to update the relative web interface?

In vw i use MADescriptioBuilder default flash .

Question C)

When i need to use [ ....] asDynamicObject?

If i use options: TitleDatabase asArrayOfInstances

it's enough to have options update to last version or ....?

Any pointers would be greatly appreciated!

Thanks

Dario

Pier uses Magritte heavily and it has been ported to GemStone.

Not #flash, #flush ;-)

If the the value within ... changes dynamically.
