Listview and hibernate question: Objects don't get deleted before the listview getObject() is called
I find that when I delete objects from my ListView, my model object for the ListView still contains a reference to the object. When the view tries to render, the object is already removed from the database and I get a null response on my hibernate load(). I use opensessioninview and when I check my logs, the delete statement comes way after the view was rendered. It seems that ListView renders the new view before the transaction is closed (but even then, the delete should be visible to later sql in the same transaction). Any ideas? Regards, Pieter Log: Hibernate: delete from ABSTRACTDATASET where ID=? ListView: === ListView documents = new ListView(documents, new IModel() { public Object getObject() { return getDocumentList(); }

How are you managing transactions?

No, my DAO's inherit from HibernateDaoSupport and I just go with the defaults.

Re: Listview and hibernate question: Objects don't get deleted before the listview getObject() is called
Yes, I reload the objects using my DAOs but, I have 2 MySQL databases on the backend and so far have not been using @Transactional. This might be the problem. Now I just have to figure out to configure tx:annotation-driven transaction-manager=txManager / for more than one transaction manager and make sure the different DOAs use the right txManager.

Looks like if you use Spring 3.x, you can do it. You have to use the value of the @Transactional annotation to figure out which tx manager to use.
