Serializing optional values [message #628954]

I get an error when trying to save a file that I am modifying using EMF calls from a separate editor (not an xtext text editor). (Actually it is worse than that since it removes the entire contents of the existing file)

The error says to consider implementing ITokenSerializer$IValueSerializer, but there does seem to be to override this in my RuntimeModule.

Here is an snippet of the grammar.

ThisOrThat returns ecore::EString:
'THIS' | 'THAT' ;

ExamplePolicy:
'POLICY' count=IntVal ThisOrThat ;

options?

Hi Drew,

feel free to add a binding to your runtime module. Just define a method:

public Class<ITokenSerializer.IValueSerializer> bindValueSerializer() {
return MyImpl.class;
}

The framework will call your method reflectively and thereby register
the binding.

Regards,
Sebastian

In your grammar snippet, the call to ThisOrThat should be assigned to a
feature of Example Policy.
