Cannot move discretionary stage (CMMN)

I tried out modeling CMMN. At some point when moving a discretionary stage the library blows up with

TypeError: Cannot read property 'source' of undefined

This happens only in conjunction with the entry / exit criterions configured according to the diagram shown below.

How to Reproduce

Move stage S to case plan model Plan B.


cmmn-js v0.4.0

Was a bug in diagram-js that got fixed with v0.15.4.
