This hibernate 4.1 example is not reading the associated key.
There were two problems with the extant code.
1) The use of Datasource.get(String) did not work at all.
2) The valueXPath display field exactly as supplied in the city data source (below) does not display. This is the critical issue. The code as copied almost directly from the showcase should work. The showcase appears to mask a problem.
Be sure your post includes:
1. SmartClient Version: v9.1p_2014-04-09/Pro Deployment (built 2014-04-09)
2. all InternetExplorer 8-11, Chrome 29, Firefox 29
4. for any problem processing a server response, the actual response as shown in the RPC tab in the Developer Console
