Hi,

I try to read a model within a mwe2 workflow without validation. My reader component looks like this:

	component = org.eclipse.xtext.mwe.Reader {
		path = modelPath
		validate = {
			validateAll = false
			stopOnError = false
		}
		register = ttt.exchange.export.graphml.GraphMLGeneratorSetup {}
		loadResource = {
			slot = "model"
		}
	}


Unfortunately it does't work. The workflow stops with errors (i removed some errors):

Is there any way to disable the validation?

hi,

yes just set a 'nullvalidator' in the component

component = Reader {
...
validate = NullValidator {}
}



public class NullValidator extends org.eclipse.xtext.mwe.Validator.Disabled {

}

Thank you. Now no errors are printed.
But now i get a BasicIndexOutOfBoundsException:

I get this exception only with the NullValidator - even with a valid model.

The Validator does resolving, so if you do not use it you have to care about resolving yourself e.g. use ecoreutil.resolveall

Ok i solved it:
public class NullValidator extends org.eclipse.xtext.mwe.Validator{
	@Override
	public void validate(ResourceSet resourceSet, Registry registry, Issues issues) {
		List<Resource> resources = Lists.newArrayList(resourceSet.getResources());
		for (Resource resource : resources) {
			try {
				resource.load(null);
			} catch (IOException e) {
				throw new WorkflowInterruptedException("Couldn't load resource (" + resource.getURI() + ")", e);
			}
		}
	}
}

Anyway i don't know if that code is clean or just a "workaround". Is that solution OK?

The clean solution is to validate! Wink

I preach it all the time but they do not listen, so i have to work sometimes with a invalid model. And for this step no valid model needed.
