Description
PlantUML throws an exception when generating SCXML (-tscxml) output for diagrams where substates are implicitly defined using dot notation.
For instance, the following code works correctly:
@startuml
state A {
state x
}
A.x -> B
B -> [*]
@endumlBut this code throws an exception:
@startuml
A.x -> B
B -> [*]
@endumljava.lang.NullPointerException

Image outputs (SVG, PNG, …) are not affected; both codes correctly produce the expected following image:
