Can you try setting the loglevel for ConnectionBus to TRACE? Do the logs show any database queries? Another thing you can try is to set up one of the mappings to execute a Microflow, then log something there to see if it's fired.
You should try to turn on xml mapping validation (if you did not do that already). This option is turned off by default which could lead to the described problems when the message you receive does not validate. You can turn this on in the mapping at the propperty Validate against schema.
Another thing that helps is to use microflows in your mapping and put in a breakpoint in your microflow that way you can see if it is triggered or not.
Thanks for this option, but the logs only show an update statement for a log item which i'm updating after calling the webservice.
I've also tried to use a microflow to retrieve the imported object and added logging to the microflow. No result.
Seems like the webservice doens't use the xml domain mapping, the microflow isn't fired??
@Pieter : turned on validate against schema, but nothing changed. Still no error message and still no documents.
Any other ideas?
