GWT import com.google.gwt.user.cellview.client.CellBrowser Problem

I am using GWT 2.1 but I am getting an error when importing this

import com.google.gwt.user.cellview.client.CellBrowser;

it is giving the error

The import com.google.gwt.user.cellview.client.CellBrowser conflicts 开发者_如何学Cwith a type defined in the same file

I have tried in an emmpty project but getting the same error. Does somebody know about this??

as a quick fix, try referring to com.google.gwt.user.cellview.client.CellBrowser using the fully qualified name rather than importing it.
