Hello

Next time use code tags

About the error stack trace

[org.springframework.webflow.execution.ActionExecutionException: 
Exception thrown executing [AnnotatedAction@138c63 targetAction = 
[SetAction@1ad98ef name = viewScope.hotels, value = searchCriteria.getDataModel(bookingService)], 
attributes = map[[empty]]] in state 'reviewHotels' of flow 'main-flow' 
-- action execution attributes were 'map[[empty]]'] 
with root cause [java.lang.Error: Unresolved compilation problem: 
Type mismatch: cannot convert from HotelLazyDataModel to DataModel<Hotel>
]

Post here the code of such state and check the two data models.
