GWT version: smartgwt-4.0d (nightly20130604)
Problem Description:
When modifying an existing data, double click this record and display a new window which holds each field, and one of the fields needs to use a SelectItem Component .
But the SelectItem displays a blank after something flashing by, and no default value has been selected .(it displays correctly at smartgwt-3 version )
no error has been reported. Here is the snippet of my code . Did I leave out any attributes?
code:
sorry of my pool English.
