Right, getting at the underlying IDataProvider is a better solution.
Thank you :)

clearCachedItemCount() is part of an internal contract. I don't see why the
code you mentioned is part of the dataview. You can write a
LazyDataProviderDecorator that would implement the count() just like what
you described:
LazyDataProviderDecorator {
int count() {
if (delegate.count()==0) {
initializedelegate();
}
return delegate.count();
}
...
}
Does that make sense?

Subject: [Wicket-user] DataView.clearCachedItemCount()
Hi Igor,
I'd like clearCachedItemCount() to become protected
(right now it is
private) because my code does the following:
- Check the number of images in the DataProvider
- If the image count is zero, it means we need to
lazily-initialize the image gallery (where the DataProvider
is reading from)
- Populate the gallery, reset the itemCount and continue ...
- Rendering process kicks in, it should see a non-zero value
for item count.
Is this a decent use-case? Are you fine with upgrading
accessibility to protected?
Thanks,
Gili
