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();
}
....

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

How are you managing transactions?

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.

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.

are you using a loadable detachable model or?
