JvmModelInferrer and JvmModelGenerator: generating error-less elements [message #1145431]

Hi,

Here is my problem.

I have a DSL that define one metamodel type that can be instantiated multiple time in a given model.

I defined in my JvmModelInferrer and infer method for this metamodel type.

I have a model where I declare several elements of this metamodel type, and one of those has errors, but the others are ok and do no refer at all to the element with errors.

Why the JvmModelGenerator does not generate the corresponding java code for the error-less elements?
Is it possible to do so?

Thanks

By default code generation is turned off in case of errors.
You can activate it by subclass BuilderParticipant and overriding
shouldGenerate(). You active (bind) the new subclass by adding the
following method to the <MyLanguage>UiModule class.

public Class<? extends IXtextBuilderParticipant>
bindIXtextBuilderParticipant() {
return MyBuilderParticipant.class;
}

Ok, cool, now I just have to find a way to disable generation for the elements with error, but I don't think that will be very hard, I can just hook up into JvmModelGenerator Smile

Thank you

Hi,

So, I'm a bit stuck:

Given an element of my model, check that there are errors or not inside this element.

In org.eclipse.xtext.builder.BuilderParticipant.shouldGenerate(Resource, IBuildContext), the check of presence of errors is done at the file level: I would like to do the same but within one element Smile
