User development, A new message was posted in the thread "Automatic transition from wait state - is it correct?": http://community.jboss.org/message/529459#529459 Author : Peter Meggitt Profile : http://community.jboss.org/people/jbossphan Message: -------------------------------------------------------------- I haven't moved to 4.3 yet but I assume the unique constraints are the same. There are 2 unique keys, one with dbid, and one with id. For some reason it looks like a new "Execution" is created which would require a new id. This would be expected from a fork. Is it also required when using a timer?   It sounds like a new "Execution" is being created and the "id" includes the "id" of the main "Execution" along with the name of the current activity. Not sure where the new "Executions" gets created and then deleted. Maybe I not thinking clearly. Can someone explain the whole purpose of the "id" column and uniqueness constraint and what queries it would be used in? -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/529459#529459
