Hi, Ujjwal
Thank you for response!
Alright, pretty reasonable.
But is it considered the best practice? It is confusing that Data Type has such declarative behavior.
I considered that all process related rules should be stored inside of the Work classes and Data classes are just Data Models for our processes.

Well yes may not be best approach to use only with Data Type, but certainly a good design when using data Class structure under pyWorkPage or aother work class page.

HI Alex,
It depends on the operation that you intend to carry out. If my top level class for the property concerned is Work- then we would go for Declare Expression on work Class.
For eg MyApp-Work :- Properties ->> TestPage(MyApp-Data) -> D1, D2 , D3
MyApp-Data :- Properties->> D1,D2,D3
For above structure lets say we intend to create Declare Expression on Property D3 (Defined in Data but also included in Work using TestPage Definition).
In my case if I need to trigger something Declaratively based on Value of D3 with/under context Of Work Page, I would create Expression under Work Class.
Other wise it would be Data Class.
