JWt

There is a documentation bug for WAbstractItemModel:

http://www.webtoolkit.eu/jwt/latest/doc/reference/jwt/eu/webtoolkit/jwt/WAbstractItemModel.html#getData%28eu.webtoolkit.jwt.WModelIndex,%20int%29

"If your item does not specify data for a particular role, it should simply return a boost::any()."

boost::any appears to be a reference to WT, not JWT.

The documentation here also seems to assume that the concept of a role should be apparent, which it is not.

It seems to me the documentation of table rendering would require more elaborate descriptions.
