I'm trying to create an Xref object from within Python, but somehow cannot set certain parameters (like the Reference and Proxy Reference). Is there a way to add an Xref to a scene using Python?
A similar thread from the legacy forum seems to indicate it is not possible, but then that was years ago, so I hope this may be possible now.

Hi @r_gigante!

Looking at this thread, it looks like the only way for me to register and use my own error types, requires me to put them into a separate framework, instead of just defining them as part of my project, as well as actually copying them into the SDK folder. Is it only me or is this mindblowingly clumsy and tedious? Or am I just getting this wrong? This makes the Cinema 4D error handling system so much harder to use and embrace.

It would be great to know whether this is just a misunderstanding on my side (which I sincerely hope it is). Also the documentation is not really clear on this there is example code how in the regular SDK docs which make it look like a piece of cake and they are lacking any reference to this disproportionate complexity introduced to just add twenty lines of code for a custom error handler.

I am trying to get all our developers to use and embrace the new error handling, but this feels like it will make my life pretty hard in this regard. :-(

Any further clarification very much appreciated.

Hi everyone,

I am creating a job that does some potentially long-ish computation in a queue in the background. To that job I added an finish observer like this:

_job.ObservableFinished().AddObserver(ConcurrentGeneratorObjectData::WatchGeneratorFinished) iferr_ignore();

The _jobvariable in this example is of type maxon::JobResultRef<BaseObject*>.

The WatchGeneratorFinished() observer function just fires an EventAdd() when the job finishes, which is usually what I want. There are, however, certain events in the scene that I am listening to which indicate that this is not the behavior I want (e.g. an editor render being kicked off) in which case I would like to remove the observer (to potentially add it back again later). I did find a function ObservableBaseInterface::RemoveObserver(), which appears to do what I want, but I am having a hard time finding out how to use it. The ObservableFinishedBaseobject that is returned from JobResultRef<>::ObservableFinished()` function I am using does not seem to implement it. Is there a way for me to do this?

Any pointers very much appreciated!
