Documentation bug: boost::any() in WAbstractItemModel
There is a documentation bug for WAbstractItemModel:
"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.
