Elements missing from imported file

Flowable Application
1

If I create a model using a pool and swimlanes to this effect:

test_model
test_model744×465 7.03 KB

All elements outside of the pool/swimlane(s), with exception of the sequence flows are ignored in the resulting BPMN exported file.
You can see this in the modeler rendered preview as such:

test_model_view
test_model_view693×426 3.67 KB

The resulting xml (Only the process element is included for brevity):

This was discovered using the modeler bundled with Flowable 6.6.0

I would need to check what the behavior is here or what is intended in the BPMN spec. What’s your use case of modeling it as such vs putting in inside the pools?

The model was used for demonstrational purposes, but there’s a bug with the modeler in that the pool and the lanes rendered couldn’t be extended beyond their first drop in on the canvas. Any attempt to do so would shorten their width. My intention was to finish the model and then edit the xml to increase the pool length.
