Hi,

is it possible to use the @ComposedChecks-Tag to register some customvalidators in the
default MyDslValidator.xtend - class?

I have some problems doing this, cause an error appears in the MyDslValidator.xtend class:

error: The value for an annotation attribute must be a constant expression

I found the problem!

It is not allowed to use these brackets : {} in the @ComposedChecks in a .xtend class

Solution for the use in a .xtend class:
//without {  } -brackets
@ComposedChecks(validators = CustomValidator )

Thanks!

This is not part of the new Xtext 2.5 documentation, isn't it?
