If I read a Person and Phones in one session, then make a change to a Phone ...Hibernate version: 3.1.2 Short description: I'm using merge (for reasons I won't get into now) to persist an object graph containing multiple new entities.Now I do a merge so that I can save the updates to the parent object. I am trying to model a parent child relationship with a one-to-many and cascade="all" option.I didn't go for bidirectional relationship because I always traverse from parent to child.The persistent objects from the server are retrieved and passed onto gui where they are manipulated and sent back to server.Thus the objects I deal with in the update are transient/detached.

One thought on “jpa entitymanager merge not updating”

  1. My question is, if the date field was initially NULL how do I set it back to Null ?? ) I changed that and I was able to trap the value properly, but I am unable to set e. So, I re-wrote my test to allow an empty string ("") - something like Is Date(e. Formatted Value) "" But then of course the Data Grid View went crazy because it would not recognize and empty string as a valid date, so I changed my SQL code to cast date fields as Char types to trick the Datagrid View.
