Hi,
I have a page where I am using a PropertyModel to populate a ListView, so it
will change when the underlying contents change:
ListView newsDetails = new ListView("newsDetails", new
PropertyModel(this, "articles"))
{
protected void populateItem(ListItem item)
{
final NewsDetails nd = (NewsDetails)
item.getModelObject();
item.add(new Label("articleDate", nd.getArticleDate()));
item.add(new Label("articleTime", nd.getArticleTime()));
item.add(new Label("newsShortDesc",
nd.getNewsShortDesc()));
newsUrlLink.add(new Label("newsTitle",
nd.getNewsTitle()));
item.add(newsUrlLink);
}
};
add(newsDetails);
The page class, obviously, has a getter named getArticles():
public List<NewsDetails> getArticles()
{
....
}
However, this seems to get called multiple times when the listview is being
populated, not just once at the beginning of each time the page is displayer.
Why is this happening? It results in many more hits to the database than are
necessary.
Thanks,
Andrew B
