Scope Provider is not deterministic. [message #673627]

I'm using XText version 1.02 and I have a problem with my scopeprovider.

Scoping in the editor behaves differently depending on how the file containing my language is opened when the
Workbench is started.

I have 4 cases:

CASE 1:
All tabs are closed when workbench is started and I open the file with my language.
OUTCOME 1:
Everything is fine and the right scopeprovider gets called.

CASE 2:
Only a file with my language is open when workbench is started.
OUTCOME 2:
Everything is fine and the right scopeprovider gets called.

CASE 3:
Empty file with right filename extension is open when workbench is started. Then I open the file with my language.
OUTCOME 3:
My scopeprovider is not called but instead a scopeprovider on a higher level which I cannot use.

CASE 4:
A valid language file is open when workbench is started. Then I open the file with my language.
OUTCOME 4:
My scopeprovider is not called but instead a scopeprovider on a higher level which I cannot use.

Have you seen this before?

Hi Ib,

what do you mean with 'ScopeProvider on a higher level is called'?
If you plugin.xml is valid (no duplicate editor registrations for the
very same file extension etc), Xtext will always take the scope provider
that was registered in the module of the right language.

Regards,
Sebastian

Hi Sebastian

I have a scopeprovider attached to my model. As I understand it the method names and the method signature decides which methods gets called in my scopeprovider.

Depending on HOW I open my language editor different methods gets called.

With "on a higher level" I mean another method is called in my scopeprovider that relates to a higher level in my model hierarchy and the best matching scoping rule is never called.
