Is pushing manually (in the code) events for write only attributes supported? set_archive_event for example is accepted as command and let clients to subscribe to it but then it seems like push_archive_event is only setting the "read part" of the attribute and in fact extract_set called by clients throws exception. Am I missing something ? |

Hi, Yes, pushing manually event for WO attribute is supported. However, I confirm the in-coherency described in your post. In such a case, the DeviceImpl::push_archive_event() does not set one of the internal DeviceAttribute data. This is what triggers the exception in the event callback if you try to use DeviceAttribute::extract_set() method. This will be fixed for next release and I am going to register a bug entry in order to not forget the fix Regards Emmanuel |
