Summary0011568: Heartbeat uses multiple database connections and closes connection too early
DescriptionThe src/org/openbravo/erpCommon/ad_process/TestHeartbeat.java class uses multiple db connections to read information from the database and commits a transaction to read the data again in the next step in a new connection.

The early commit results in errors in hibernate because an object is not linked to a session anymore.


gr. Martin
Steps To Reproduce
Proposed Solution
The solution is to use DalConnectionProvider and use one connection for all steps.

One more change is needed for this issue.

When a new ProcessRequest is created then the OBScheduler is called. However, the OBScheduler uses its own connection provider. If the transaction is not committed before the scheduler is called. Then the OBScheduler won't see the ProcessRequest if it is new.

So before calling the OBScheduler a commit has to be done.
