Hey everybody,
I got a question concerning the collapsible Panel Tag of MyFaces. I
have several objects inside a database and I added the
"toggleCollapsed" boolean Attribute to the bean.
So that's what the Comments Bean looks like. Just a few getters and
setters, filled by hibernate. Hibernate doesn't touch the property for
the panel.
BUT: When I expand the panel, all of the objects expand and not only
the one I selected. To get this straight: the datatable iterates the
objects inside the list. So each object has a different
"toggleCollapsed" property.
Why does the panel expand all the objects? Here's a screenshot of both
states and the source of the JSF Code.
![panel]()
I'd be glad if anybody could help me with that.
If I am not rebuilding, you can check it out for yourself:

Thanks in advance,
