Searching old messages I have found that everybody strongly recomend that business objects should not have any visual components. Like Pamela Thalacker writes: "The best design I have found is to make all business objects children of the form". I understand that it's the best way to get the n-tier philosofy
I have read too the article from C.T.Blankenship in the last NewsLetter and his particular way of implementing the tiers.
1) Build a Business Object, with no visual components: bo_Test
2) Build a Business Object Interface: boi_Test, subclassing bo_Test and adding all the visual components we need.
3) Build a Business Object Form, where to instantiate boi_Test
Really I can't see if this procedure is good or if is broking any rules of n-tier implementation.
Has anybody ideas about it?
TIA
