i am a xtext new member.when i use this ,find a problem.
i use XtextResource.save(OutputStream outputStream, Map<?, ?> options) it occur a Exception .
my code is :
URI uri = URI.createFileURI(path);
Resource resource = new ResourceSetImpl().getResource(uri, true);
processType = (ProcessType) resource.getContents().get(0);
...
XtextResource xResource = (XtextResource) processType.eResource();
...
SerializerOptions op = new SerializerOptions(false, true);
map.put(XtextResource.OPTION_SERIALIZATION_OPTIONS, op);
xResource.save(new FileOutputStream("d:\\b.txt"), map);
note:the path file is script4_0.1.jobscript which is attached.
the Exception is :
org.eclipse.xtext.parsetree.reconstr.XtextSerializationException: Serialization failed

Hi zwzhao,
the member has to be populated with valid values for its references and
attributes according to your grammar.
Consider the following example:
NamedThing:
'thing' name=ID (desc=STRING)? attr+=Attr (attr+=Attr)?
(left?='left'|right?='right);
If you create a NamedThing in memory, it has to have a name (mandatory
feature), it may have a desc and it must have at least one element in
its attr-list but no more than two. Either left or right have to be true
but at least one of both has to be false. Most grammars introduce more
constraints which are not that obvious as in this example.
The exception indicates that your created member is incomplete.
Does that answer your question?
Regards,
Sebastian
