How can I use JvmModelInferrer and old Generator approach in parallel [message #1690899]

How do I have to configure my Xtext project to enable the use of JvmModelInferrer and the old generator parallel in one project ?

I already have the following in my mwe2-File:

    		// generator API
    		fragment = generator.GeneratorFragment auto-inject {}
                ...
    		// provides the necessary bindings for java types integration
    		fragment = types.TypesGeneratorFragment auto-inject {}
    
    		// generates the required bindings only if the grammar inherits from Xbase
    		fragment = xbase.XbaseGeneratorFragment auto-inject {}
    		
    		// generates the required bindings only if the grammar inherits from Xtype
    		fragment = xbase.XtypeGeneratorFragment auto-inject {}

The basic generator class does get generated but it is not called when I save my model.
What is wrong ?

Hi,

the jvmmodelinferrer uses its own igenerator: jvmmodelgenerator. thus you should subclass jvmmodelgenerator

or create another IGenerator as generator root, inject the JvmModelGenerator and dispatch to it and the other templates.

I created my own IGenerator implementation:

class IGeneratorRoot implements IGenerator {
	
	@Inject
	JvmModelGenerator jvmModelGenerator
	
	@Inject
	ContentProviderGenerator contentProviderGenerator
	
	 
	override doGenerate(Resource input, IFileSystemAccess fsa) {
		jvmModelGenerator.doGenerate(input, fsa)
		contentProviderGenerator.doGenerate(input, fsa)
	}
}

and added this to my RuntimeModule:

public Class<? extends ContentProviderGenerator> bindContentProviderGenerator() {
	return ContentProviderGenerator.class;
}

@SuppressWarnings("restriction")
public Class<? extends JvmModelGenerator> bindJvmModelGenerator() {
	return JvmModelGenerator.class;
}

@Override
public Class<? extends IGenerator> bindIGenerator() {
	return IGeneratorRoot.class;
}

but I get the following error:

I guess there is something wrong with the injection.

I dont think so can comment the call of your generator out and retry. Maybe you have an error in your inferrer as well

Sorry it was an error in my ModelInferrer code.
