I'm developing a GMF editor and I need to model a certain attribute as a Map. I'm following this wiki to do it. But in the property sheet of instances of that class (in the GMF editor) the attribute is not shown. Is this the expected?

Also: Where I can find some tutorial/doc about adding support to edit the map entries(and to create/modify objects that are not represented in the diagram)?

Thanks for everything.
(Sorry if this question should be posted in the GMF sub-forum...)

Yes, that's expected. Map entries are essentially just contained
EObjects and are created using "New->" in a structured editor.

I imagine typically such editing could be done in the outline view, no?

Thank you, Ed! Comments below:

Humm.. you're right... I can add those maps using the "New child..." action.
And seems that I also can show the attribute in the property sheet (by setting
"property type" to "editable" in the edit section of the class in Genmodel)
and let users select (existing) instances of the map to compound this attribute.

I'd tried your hint and you're right.
But, in this context (the GMF-based editor), it will be a bit counter-intuitive
for the users if I ask them to head to the outline view and add the map.
I think the best approach would be using the property sheet itself to set the attribute.

Maybe I could by setting "property type" to editable and try to extend the wizzard
that opens to edit it (bellow) to add an option to create a new map entry and to
edit this entry in the same window.

index.php/fa/17783/0/

Do you think it's a good approach (or that exists a better way to do it)?

Ricardo,

Yes, making the containment reference an editable property and providing
a specialized property editor for editing the overall map is a
reasonable (and nice) approach.
