Seam 1.2.1-GA, JBoss AS 4.2.1, Hibernate 3.2.5ga
I wish to put a button on a form that adds an item to a list being displayed/edited in a
dataTable. The new item is not completely initialized -- until the user types in some
values in the table columns, it's not ready for persisting.
On my MyHome class, I have a function
| public void addItem() {
| getInstance().myList().add(new SomeEntity());
| }
|
The problem is that after calling addItem, something is deciding to commit the new
SomeEntity to the database. I don't want it to try to persist until I explicitly call
em.persist() or em.update(). How can I stop it from persisting the object?
I've tried several types of button markup:
| <s:button action="#{myHome.addItem}" ...
| <h:command action="#{myHome.addItem}" ...
| <h:commandButton immediate="true"action="#{myHome.addItem}"
...
|
... and no matter what I do, hibernate is deciding to commit a transaction when I call
through the button. Help!
The stack in case that helps:
