An ambigous exception on unknown type serialization

[rothschild86]

If there is a Java.util.date property on the entity, "Failed to instantiate model class - does it have a public null constructor?" exception is thrown.

In this case it happened because Entity.load() method swallowed IllegalArgumentExeption and replaced it with ORMDroidException.

catch (Exception e) { throw new ORMDroidException( "Failed to instantiate model class - does it have a public null constructor?", e); }

Perhaps ORMDroidException should at least print e.getClass() for the original exception?

But even then IllegalArgumentExeption does not quite indicate that there was a problem with type serialization. Needs better handling?

On the subject of dates, since util.Date, maybe it is worth serializing it (maybe not)? Azure Mobile Services handles it this way and it works quite well:

Fixed in master. Will make next release.

Thanks for the report!

This fix brings in a (minor) API change, in that it removes the default mapping. If your code relies on it you must now set the default mapping manually using TypeMapper#setDefaultMapping.
