I have an Entity implementing a lazy TBlob-Field saving RTF Text.
This Entity is loaded in a TAureliusDataset using SetSourceList.
Fields are generated from TAureliusDataset while opening.
Because my Blob is lazy, it is not loaded immediately.
(but I think Lazy should be ignorred for Blobs, if it is part of a Dataset)
Apart from this, Blob is loaded afterwards and saved to my Entity, so that it will not reload later on.
But setting Blob-Field just marks it as changed, so that TObjectManager.HasChanges will return true.
Just saying this in an easy way, creating Fields in a TAureliusDataset for Lazy loaded blobs will cause that TObjectManager.HasChanges will return true, because of setting Blob-Field while loading it lazy
