Hi there, 

This seems to be a GWT 2.5 issue. 

I have two ValueProxy: Data and DataDetail, DataDetail extends Data, both 
are proxy for backend entity DataEntity.  DataDetail has more properties 
than Data does. The reason I have two proxy for one single entity is 
because I want to load a list of Data objects first and then for a given 
Data object, load all its details as DataDetail.   This is how I implement 
loading-details-on-demand so that I do not load too much data in the 
beginning. 

List<Data>  getAllObjects();                 <=== load only minimum set of 
data for all objects
DataDetail   getObjectDetail(id);            <=== load as much as I can for 
one object

If I have DataDetail extending Data, then GWT is always loading all 
properties in DataDetail (even for getAllObjects() call), because 
ProxyAutoBean is loading properties defined in DataDetail, even though the 
interface is only using Data value proxy. 

But if I have DataDetail duplicate properties in Data (thus I do not need 
DataDetail extends Data), then everything works as expected. 

Is this a GWT bug?

Thanks,
yan
