Re: [Wicket-user] list view sorting consuming all heap space
Everyone, thanks for the help. I finally found the problem by debugging into componentModelChanging as several people had urged me to do. The memory hog was an object I had in the data provider, which was a member class of my Page class. I wasn't using the page in it, but it still had compiler generated references to the page object. Therefore, it was huge. Seems like a pretty easy trap to fall into; if a view object sneaks into a model somehow, your session is headed for disaster. Wouldn't that mean you can never have an anonymous subclass of Model in any kind of Component? I feel like I've seen that all over the place.

Re: [Wicket-user] list view sorting consuming all heap space
I guess if you subclass model, you have to make sure you turn of versioning on the component. I neverthought of that before. That's a tricky one.

Re: [Wicket-user] list view sorting consuming all heap space
I did eventually update to the detaching HibernateDataProvider, but
still ran out of heap space. That one object wouldn't have amounted to
enough memory anyway. Somewhere, something recursive is broken.
Clicking through the sort header, response times get noticeably slower
with each request until it crashes. I'm sorry that I won't be able work
on it anymore this week.
If no one has confirmed that DataView sorting works properly and
indefinitely with HibernateDataProvider, it would be a good project.
Wicket can't really take off until there's an easy, standard way to
view and sort hibernate query results.

Ahh, I see. Didnt notice you were using
a subclass of the dataview. Either way, though, the exact same problem remains
because the HibernateDataProvider stores the instance of ihibernatedao you
retrieve very bad! The HibernateDataProvider should be using the same
kind of decoration that I provided below for the IDataProvider where the
location logic for locating the underlying dao is moved into the decorator.

Re: [Wicket-user] list view sorting consuming all heap space
Ok, that change is going into cvs? I don't see any new constructors yet.
(I titled my first message "list view" because I had the same problem
with contrib.data's OrderedPageableList. No one's talking about that
one though.)

Sorry about that. I totally spaced this thread because it was called
"list view". Anyway, I added constructors to HibernateDataProvider and
HibernateModel that take IModels for the IHibernateDao for the case
when you want to do a lookup. For example:
IModel lookup = new Model() {
public Object getObject(Component component) {
// Do some Spring lookup stuff here and get an IHibernateDao...
}
}
new HibernateDataProvider(lookup) {
// Define abstract methods...
}

Ahh, I see. Didn't notice you were using a subclass of the dataview. Either
way, though, the exact same problem remains because the
HibernateDataProvider stores the instance of ihibernatedao you retrieve –
very bad! The HibernateDataProvider should be using the same kind of
decoration that I provided below for the IDataProvider – where the location
logic for locating the underlying dao is moved into the decorator.

I don't see how that code would work, as my bean isn't an instance of
IDataProvider; it's an IHibernateDao. Is there an example somewhere of how
DataView works with hibernate in such a way that the data provider isn't
entirely serialized? At the moment I'm trying to wrap my
HibernateDataProvider in a detachable model, which is harder than it seems
like this should be. Perhaps I'm not even supposed to be using a
HibernateDataProvider.

When I turn off page versioning, the problem goes away. I'm not
holding on to any big objects though, as far as I can tell. There are
some ExternalLink components in the list which aren't detachable, but
I don't see that using all my java heap space.
There are other controls on the page which affect the query. I can
toggle them up through version 33 without any problem; it's only the
sorting that gobbles up memory until it crashes.

Re: [Wicket-user] list view sorting consuming all heap space
if you enabled versioning can you debug into Page.componentModelChanging(final Component component) ? And see what is serialized of the model? Something must be versioned that is pretty large.
