I am looking for a WorkflowComponent implementation for executing .qvto
transformation from .mwe scripts (Eclipse EMFT Modeling Workflow Engine).
Do you know any such implementation? If not, some directions how to write
one would be wonderful.
Thanks,
Ioan

Hi Ioan,
In case you are trying to run standalone (no Eclipse),
the bad news is that QVTo does not support this yet, though you can
use a headless eclipse application.
However, the good news is that we plan to support that in early milestones
of the next release.
Obviously, we should have handled such a situation gracefully, check for
the extension
registry availability and drop an explaining message.
Sorry for not clearly manifesting this limitation, the doc material is
always behind
the implementation due to lack of resources ;(.
We will improve that just after the Galileo release.
Regards,
/Radek

Hi Ioan,
Unfortunately, the current invocation API does not give you access to
traces.
The trace meta-model is still internal, though we could support the trace
serialization
at a user provided URI. Will be solved by
https://bugs.eclipse.org/bugs/show_bug.cgi?id=282645.
If it's essential to your application and you need to stick to the
released QVTo 2.0.0, you could
use a custom transf. executor class based on the #282645 resolution.
Regards,
/Radek

Hi Christoph,
We have done a great progress in Eclipse dependency cleanup, but need to
complete
the blackbox support outside Eclipse. Also, it still requires
some extra testing.
Yes, it's still planned.
