| Serializing a manually created xtext model [message #486953] |

Dear Xtext team,
I have created a grammar, say MyDsl.
Using the MyDslFactory class, Ive created a model and would like to serialize it into the textual representation.
In my grammar I have an annotation terminal rule:
terminal ML_DESC returns ecore::EString : ('@desc') WS* '{' -> '}';
How do I configure the serializer to include this terminal rule so that the textual representation will display the"@desc" with the description annotation.
So far, I have been able to print out the value of the annotation without the "@desc".
In my code, I have created the model, and added it to the contents of a resource before calling save. Therefore, the XtextResource does not have a parseresult.
Any hints into the right direction would be appreciated!
Many thanks
Dana

Hi Dana,
did you implement a value converter for your ML_DESC?
The toString(String value) should prepend the @desc keyword before the
actual value of your comment.
See
http://www.eclipse.org/Xtext/documentation/0_7_2/xtext.html# valueconverter
Hope that helps,
Sebastian
