Hi,
I have set up an application with MyFaces Orchestra. It seems to work fine,
except that no transaction is committed at the end of the conversation. I
tried both "access" and "manual" conversation scopes, both with the same
result. I'm probably missing something. Can someone assist me a little bit
here? Below are some snippets from the most important files in my project.
Best regards,
Bart Kummel
