How can I check feature assignment is ok? [message #843100]

When I'm testing my DSL in another eclipse instance I can see at Outline View the elements being fulfilled. Each element o that view is named with the primary EString property/feature value.

But I want to see the values of other properties of the selected element to check if assignment is being ok. Properties view shows me nothing...

Is there any way to do that?

thanks

Well,

I can confess to you that I'm buzzy reading and rereading this one first http://www.eclipse.org/Xtext/documentation/2_1_0/020-grammar-language.php because I could not finish the grammar yet.. I'm bitten by some not nice ambiguous erros...

I never hear about such overview api, and probably won't have time for that so soon. I just thought that I could have same information that Properties View gives me using ecore editor when editing a ecore model...

regards,

Cristiano

Hi,

am not quite sure what you are now talking about.
in your first post you were talking about the outline.
the outline shows the structure of the model.
of course you could change it so that it shows the whole model.
but therefore you have to customize the Outline as described here (especially "Influencing the Structure")

Btw did you try to open the .mydsl file with "sample (reflective) ecore model editor" - this might help you if you really want to "test" your grammar - id prefer a unit test in this case.

Well, sorry for not be that clear... english for me sometimes is not that easy to express...

I'll try to explain.
Supposed that I have a ecore model file and I have generated an Editor and Edit projects from it using genModel.
I use the generated editor to include some instances and there are an out-of-box properties view and outline view integration.
When editing the model, if I select one element instance in the outline view, I can see all its properties in the properties view.

When editing this same model using xtext, I can see the the overview elements, but can't see its properties.
got it now ?

Humm, that will help a lot....

I will try to play with unit tests as soon I have my grammar working Smile
