How scoping works on Ecore Editor ? [message #1806538]

Hi,

I have a metamodel that is generated by Xtext from a syntax of DSL named DSL1.

Within this DSL I make a cross reference to another DSL say DSL2.

Now, I created a dynamique instance in the Ecore Editor of DSL1. I also created a dynamique instance of DSL2 in the Ecore Editor.

When I want to specify the cross reference in the Editor, it is empty (I guess there is nothing in the scope). In Xtext, the scoping is handled in the ScopeProvider.

How can I achieve that in the Ecore Editor ?

You need to load the resource you want to reference into the resource set of the editor. You can do that via the context menu, Load Resource, or by dragging and dropping the file from the workspace onto the open editor.

I tried that but it does not work, and it makes sense because there is no scope provider in the Ecore Editor ?

I got my dsl file, if you mean an Xtext project. But I use the metamodel in another project and I want to apply some transformations using ATL on the instances.

How can make a provider for xmi ?

why do you need an xmi at all.
