Hi,
I ran into some strange behavior with PropertyModels vs. "regular"
models. I set up a very simple example that demonstrates what works on
the one hand and what I would expect to work as well but does not. What
I'm doing is very basic: I'm population a list and when a user clicks on
an item in the link the details of that object are shown using ajax. The
following code works fine:
public class HomePage extends WebPage {
@SpringBean
private OrfDataService orfDataService;
private OrfData selected = new OrfData();
public HomePage(final PageParameters parameters) {
// code block to be replaced
Model<String> testModel = new Model<String>() {
public String getObject() {
return selected.getProdNo();
}
};
final Label testLabel = new Label("testLabel", testModel);
// end of code block to be replaced
testLabel.setOutputMarkupId(true);
add(testLabel);
add(new ListView<OrfData>("orfDataList", orfDataService.getOrfData())
{
public void populateItem(final ListItem<OrfData> listItem) {
// add all the listItem labels etc..
listItem.add(new AjaxLink<OrfData>("selectLink") {
@Override
public void onClick(AjaxRequestTarget target) {
selected = getModelObject();
target.addComponent(testLabel);
}
});
}
});
}
public void setOrfDataService(OrfDataService orfDataService) {
this.orfDataService = orfDataService;
}
}
However, naturally I want to do the above using PropertyModel. But if I
replace the commented code block above with the following line:
final Label testLabel = new Label("testLabel", new
PropertyModel<String>(selected, "prodNo"));
The label no longer gets updated.
Any idea what I'm doing wrong here?
Thanks, Jonck
P.S. I know the usage of the orfDataService is not really all that great
here, it's just as an example
