Is there any navigation operator for html rendering properties?
{ bookingFlow.nextStep.question } throws an exception when 'nextStep' is undefined. That exception could be bypassed using a navigation operator '?' { bookingFlow.nextStep**?**.question }, therefore making a expression like this possible:
// if nextStep is neither undefined nor null, displays its question property value, otherwise, displays the startingQuestion
{ bookingFlow.nextStep?.question || bookingFlow.startingQuestion }
