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. Author Message DWright Post subject: Unexpected update of parent in merge of parent-child Posted: Wed Apr 12, 2006 pm Regular Joined: Wed Jul 07, 2004 pm Posts: 64 I have a simple eager unidirectional 1-many relationship between Person and Phone.I have 2 basic entities "Parent" and "Child" with bidirectional orphan Removal One To One association between them.Property Access Exception is thrown when I want to remove Child entity from Parent. Child(null); entity Manager.merge(parent); entity Manager.flush(); ... When I try the same code with eclipselink 2.1.0 everything is ok. We have run into the following issue with Hibernate.

Based on the row action property on Parent/Child we call Entity Manager.merge() on Parent and Child separately (although both calls may happen in the same transaction).

Abstract Controller.handle Request(Abstract Controller.java:153) org. Simple Controller Handler Adapter.handle(Simple Controller Handler Adapter.java:48) org.servlet.

As mentioned above we are using My SQL database for database operations.

The main modules for this example are as follows: Let us take the package hierarchy which we have used in the JPA installation with Eclipselink.

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.
