increase conversation timeout to 30 minutes

The scaffold generated entity DAO beans contain two conversation.begin() commands [in the create() and retrieve() methods]

After each conversation.begin() please insert:
this.conversation.setTimeout(1800000);

which will extend the conversation timeout from the default ten minutes to thirty minutes (same as the session timeout)

For me, complex data entry screens often have their conversation expire during the period that a user composes and keys their data. Very frustrating !
