Description Stefan Holzknecht

Build Identifier: 20100617-1415

When serializing I get an error:
!ENTRY com.intershop.enfinity.studio.emf.opexpression 4 -1 2010-08-23 08:11:55.776
!MESSAGE An exception occured: null

This is caused because method org.eclipse.xtext.parsetree.impl.AbstractNodeImpl.getTotalLength() return -1. When debugging I got such a LeafNode: org.eclipse.xtext.parsetree.impl.LeafNodeImpl@1c4317c (totalOffset: 0, totalLine: 0, totalLength: -1) (text: myTest, feature: null, hidden: false).


Reproducible: Always

How do you create your model?

> How do you create your model?

Because I need the model outside the editor I use org.eclipse.xtext.parser.AbstractParser.parse(Reader).

Never do that. Create a resourceSet instead and use resourceSet#getResource or resourceSet#createResource. See here: http://wiki.eclipse.org/Xtext/FAQ#How_do_I_load_my_model_in_a_standalone_Java_application_.3F
