[SOLVED]Problem with Xtend keywords [message #1369628]

Hello,

I am using a Xtext-Typesystem-API (https://code.google.com/a/eclipselabs.org/p/xtext-typesystem/) which provides me the following operaton:

 typeof(EObject obj, TypeCalculationTrace trace);

I want to use this operation in my : MydslValidator.xtend - class, but it is not possible because Xtend reserve this operationname as a keyword.

Is there a possibility to use this operation without wrapping it in an own Javaclass?

Hi,
you made my day (or better night..)!!

Thank you! Is it maybe possible to define more than one validator? maybe one in Xtend and another one in Java?
I read something about it here: http://blog.dietmar-stoll.de/2013/04/multiple-validators-in-xtext.html but I'm not sure, that I can combine Java and Xtend validators.

you can add subvalidators using the annotation @ComposedChecks on the main validator class

Hi,

I'm a litte bit confused, cause it didn't work out for me. I'm doing the following steps:

1. Adding a composedCheck in my XTEND-MyDslValidator:

@ComposedChecks (validators = { CustomValidator.class })
class MyDslValidator extends AbstractCdalfValidator{
..
}

2. Create a Javaclass in the same validation package that looks like this:

public class CustomValidator extends AbstractDeclarativeValidator{

}

Do I have to register the CustomValidator.class also in the xtext runtime module or maybe in the .mwe2 file?
I also getting the following error in the Xtend-Validator-class:

The value for an annotation attribute must be a constant expression

Thanks!
