There is a bug in the templates used to generate a skeleton Seam application.

In the following generated class, the generated code

@DataModelSelection
private LocationTable selectedLocationTable;

should be:

@DataModelSelection("locationTablesList")
private LocationTable selectedLocationTable;

package test1.model;
