Hi everybody,

I get a strange error if I try to evaluate Xbase expressions.
My Grammar contains just a field expression=XExpression.
If I write in a .dsl file eg true && false an unhandled loop exception is thrown:

Caused by: org.eclipse.xtext.util.PolymorphicDispatcher$NoSuchMethodException: Couldn't find method ''_featureCall'' for objects [JvmVoid: (eProxyURI: platform:/resource/ololol/src/My_synthetic.pc#xtextLink_::0.0.2::0::/1), <XBooleanLiteralImpl> && <XBooleanLiteralImpl>, true, org.eclipse.xtext.xbase.interpreter.impl.DefaultEvaluationContext@1bed0884, org.eclipse.xtext.util.CancelIndicator$1@66ca206e]
... 57 more

Does anyone has an idea why this error occurs and how I could possibly fix it?
Best regards
Masija

Hi Masija,

the feature '&&' (operator_and) is not resolvable. Can you make sure
that your resource set or the project that contains the file is properly
configured (has xbase.lib on its classpath).

Regards,
Sebastian

Hi Christian, Hi Sebastian,

thanks for your replies! Sebastians hint helped me, the resourceSet which I have used was configured wrong, so the expressions couldn't be evaluated.

Best regards,
Masija
