Hi Steffen,
What you're doing looks basically correct, so I think it should be
working. What version of SDO are you using? I know that we fixed a bug in
static (generated) SDO about 1 or 2 weeks ago, that may be related to
this. Have you tried using the latest version from HEAD?
If it still doesn't work, can you open a JIRA and provide us with a JUnit
test and the necessary files to reproduce the problem?
Thanks,
Frank
