Miro,
You are right. Bidirectional references are broken in Tuscany. They seem
to have been broken when we switched over to the new (noEMF) codegen
patterns. I guess nobody uses them much and we don't have a test case. Can
you please open a JIRA bug report to track this?
I understand your point about wanting a static (non SDO dependent) way to
navigate to the container. I think this is something that we should try to
change in the next version of SDO. Maybe something like this:
<xsd:element name="lines" type="impl:SoL"
sdojava:getContainer="getOrder" minOccurs="0" maxOccurs="unbounded" />
Maybe for now in Tuscany, we could just always generate a static method
for getContainer equal to "get" + <container type name>. For example, we
would generate:
SoH getSoH() { return (SoH)getContainer(); }
in class SoLImpl. This wouldn't be standard SDO, but a generator is
allowed to generate additional implementation-specific methods and still
be considered compliant.
