Solved Implementing a custom data model for SCXML

I'm using Qt with an SCXML state machine. I want to use the native Qt SCXML interpreter via
QScxmlStateMachine. However, Qt only supports Null, EcmaScript, and C++ data models for SCXML. My state machine has a custom data model.
I would like to subclass
QScxmlDataModelto support my state machine. I can see how implementing the
scxmlProperty()functions would allow setting/getting values from the data model. However, I don't see how to make it so that expressions and other model-specific items—such as with
<script>...</script>—will properly be evaluated in my custom data model.
How can I make a custom data model that knows how to do more than just get/set properties?
