I identified the issue and this isn't related to NULL references. To
summarize:
This syntax will work with a getter method OR directly with the raw member
variable if the getter method isn't present: <@s.property
value="myActionProperty.subProperty" />
This syntax requires a getter method and won't work directly with a member
variable: ${myActionProperty.subProperty}
I prefer to avoid littering my code with unnecessary boilerplate
getter/setter methods and only define getters/setters when they actually do
something that is non-trivial. But at least this makes sense.
Thank you very much for the helpful replies!
