In "theory" the isAssignableFrom method on the underlying MetaModel & Range classes should be able to test for a legal/automatic type conversion, but it looks like that code is commented out in the current version of the Validator class. In any case, it certainly seems that using the normal reference classes for the primitive types should work fine. Nullability is another benefit of using the reference classes.

To do so, I thought I would have to provide the MetaModelProperty with a PropertyRange. The DatatypeClassRange seemed the only suitable option, but its fromStringRepresentation method loads the class through a Class.forName, so class "int", is of course not found, and the load of the PropertyRange results in a ClassNotFoundException. > > Is this a bug, is this a feature? > > Kind regards, > Niels Hoogeveen > > > _________________________________________________________________ > Express yourself instantly with MSN Messenger!
