Assuming that the line numbers in your stack trace correspond to the EMF
version (2.2.3) that I'm looking at, it looks to me like null is being
passed into the getList() method. If so, I assume it's because this line
returned null:
Property addressProperty =
context.getXSDHelper().getGlobalProperty("http://www.example.org/Address";,
"Address", true);
That is, it couldn't locate your global property.
