Skipping validations of features from EMF Model [message #995815]

Hi,

I am creating DSL for existing EMF Model who persistence format is xmi. The DSL will be just an alternate representation of xmi format.

The DSL contains many less features because i want only relevant features available to user and system specific stuff is kept hidden.
These features in DSL are marked optional in grammar. But they are not optional in ECore model.

Hence in the DSL i see error reporting that "... feature is not optional and should be specified ...". One way is to change the ECore model but I can't do this because i don't have authorizations to change the ECore model. Is it possible to skip these validation errors ?

Regards,
Ashwani Kr Sharma

Yes, you may skip the EObjectValidator in case you validate your
language files. See
org.eclipse.xtext.validation.CompositeEValidator.useEObjectValidator

Hi,

adding a simple straight forward binding to the runtime module doesnt work?

public void configureUseEObjectValidator(Binder binder) {
binder.bind(Boolean.class)
.annotatedWith(
Names.named(CompositeEValidator.USE_EOBJECT_VALIDATOR))
.toInstance(Boolean.FALSE);
}

Hi,

I have put following method in my RuntimeModule class. But nothing changes:

public void configureUseEObjectValidator(Binder binder) {
binder.bind(Boolean.class).annotatedWith(Names.named(CompositeEValidator.USE_EOBJECT_VALIDATOR)).toInstance(Boolean.FALSE);
}

I read the documentation of xText and following is mentioned there. So, can't we skip them ?
Quote:

The IConcreteSyntaxValidator validates all constraints that are implied by a grammar.
Meeting these constraints for a model is mandatory to be serialized.

Hi,

so are we talking about two things?

first you where talking about mandatory things in the metamodel that do not appear in the grammar, not you are talking about mandatory things in the grammar that dont appear in the model?
