Hi, I try to implement a default method in an interface as follows:

interface Foo
{
   def asString(String value)
   {
      if (value === null) "" else value
   }
}

The editor complains, that "Abstract methods do not specify a body". I followed the example in https://www.eclipse.org/xtend/documentation/202_xtend_classes_members.html#interfaces, but without success.
Thanks for any help!

which xtext / xtend version do you use? which java compiler level did you set on the project and in the xtend settings
