#191 Non-Standard getter/setter names and deep-mapping issue

Dozer v5.2

When using the following mapping, the objects are mapped properly, but an exception is thrown.

The getter / setter methods in the objects to map don't use standard naming. If the fieldname is explicitly excluded (see below), everything works fine.

Is that the expectd behaviour or a bug?

I'm looking forward to reading your replies ;-)

Kind regards

    By default, Dozer builds mappings between fields with the same name. In your example, dozer builds mapings:
    1. between theStringValue.theValue and theStringValue
    2. between theStringValue and theStringValue of the DeepMappingTest object.

    The second mapping cause an exception, because field types do not match. You need set wildcard="false" to your mapping and it will work fine, but in this case you'll need ti write mappings between all the rest fields by yourself. Dozer won't build mapping between attributes with the same name.

    I've added more detailed message, when argument type mismatch occurs.

    closing this issue. this was an intended behaviour. correction was made to source code to make error message look more meaningful.
