SUMMARY

I'm trying to create a competition and get the demo agent to receive notifications... this is how:

STEPS TO REPRODUCE

1. On a clean installation of tacenergy-0.6, I created a new competition with "number of participants" set to 1.
2. With a clean build of tacenergydemo-0.5, I click on "Send Ready Notification to server." and can confirm that the server recognizes the tacenergy1 user as ready.
3. A few seconds later, the demo agent fails with "2010-05-03 22:41:07,799 [jmsForecastContainer-1] ERROR tacdemo.JmsNotificationService  - Failed to save received forecastNotification as local Forecast: org.springframework.validation.BeanPropertyBindingResult: 1 errors
Field error in object 'edu.kit.iism.tacdemo.Forecast' on field 'product': rejected value [null]; codes [edu.kit.iism.tacdemo.Forecast.product.nullable.error.edu.kit.iism.tacdemo.Forecast.product,edu.kit.iism.tacdemo.Forecast.product.nullable.error.product,edu.kit.iism.tacdemo.Forecast.product.nullable.error.edu.kit.iism.tacdemo.Product,edu.kit.iism.tacdemo.Forecast.product.nullable.error,forecast.product.nullable.error.edu.kit.iism.tacdemo.Forecast.product,forecast.product.nullable.error.product,forecast.product.nullable.error.edu.kit.iism.tacdemo.Product,forecast.product.nullable.error,edu.kit.iism.tacdemo.Forecast.product.nullable.edu.kit.iism.tacdemo.Forecast.product,edu.kit.iism.tacdemo.Forecast.product.nullable.product,edu.kit.iism.tacdemo.Forecast.product.nullable.edu.kit.iism.tacdemo.Product,edu.kit.iism.tacdemo.Forecast.product.nullable,forecast.product.nullable.edu.kit.iism.tacdemo.Forecast.product,forecast.product.nullable.product,forecast.product.nullable.edu.kit.iism.tacdemo.Product,forecast.product.nullable,nullable.edu.kit.iism.tacdemo.Forecast.product,nullable.product,nullable.edu.kit.iism.tacdemo.Product,nullable]; arguments [product,class edu.kit.iism.tacdemo.Forecast]; default message [Property [{0}] of class [{1}] cannot be null]".
