Confusing error message about property type

[mkllnk]

When assigning a number, I got:

The type of the property 'http://static.datafoodconsortium.org/ontologies/DFC_BusinessOntology.owl#price' is 'BigDecimal' but a primitive, a SemanticObject or an Array is required.

While this error is correct, it would be nice to see which type is required:

The type of the property 'http://static.datafoodconsortium.org/ontologies/DFC_BusinessOntology.owl#price' is 'BigDecimal' but should be 'Float'.
