Following Tijs’s blog post [“Flowable 6 adds ad-hoc sub process support”](http://bpmn20inaction.blogspot.com/2016/02/activiti-6-adds-ad-hoc-sub-process.html), I modelled the same process in Flowable Modeler (6.2.0-SNAPSHOT). However, when I try to publish the process, app deployment fails with this root exception:

```

The process does validate correctly when I press the Validate button the modeller. Am I overlooking something?

I’ve tried it here with with the current master too, but I can deploy it without problems when I try to deploy it from a unit test or when I publish an app with the process model. Can you post your bpmn20.xml?

I couldn’t locate the original model so rebuilt it and this time it published without a hitch. Inverse Murphy’s law. What is odd is that in the Admin App, if I click “Show process diagram”, it displays only the Start Event.

lol. But good that you haven’t been able to reproduce 😉

Could be the js renderer hasn’t got support for the adhoc subprocess yet …
