setWillHandleAdvancedCriteria removed from smartgwt version 4.0

Hi Isomorphic,

I am upgrading our app from smartgwt 3.0 to 4.0. In our datasource we call setWillHandleAdvancedCriteria(boolean) but I found out that setWillHandleAdvancedCriteria method does not exist anymore in 4.0 which caused our fetch not working.

Would you please shed the light that what is the workaround for this?

Thanks in advance,
Roy
