The help in the 3.2 RC1 SDK mentions a sample (com.sabre.redapp.example.pnr) that can access PNRs, but the code is not available in the samples. This seems to be a great feature of SDK 3.0+.
Can the sample be found somewhere else?
This sample demonstrates access to PNR and refreshing Trip Summary. When you have a PNR present in your workspace you can clik on "Get PNR" button to get contents of current PNR.The result will be displayed in the text area on the left.
When you need to refresh Trip Summary click on "Refresh Trip Summary" button. You will see the refresh request status in the text area on the left.
NOTE: Refreshing Trip Summary works only in Sabre Red Workspace 3.0. In 2.0 it has no effect.
you are right, the RC does not contains this sample code. This will be fixed in our next release targeted mid-August
