Hi guys,
I'm having an issue with property models.
I have a DataView running over a number of Post objects. The Post object
has a property named "product" with appropriate getter/setter.
new DataView<Post>("posts", provider) {
protected void populateItem(final Item<Post> item) {
item.setModel(CompoundPropertyModel.of(item.getModel()));
item.add(new ProductPanel("product"));
}
}
The issue is within ProductPanel. It has a number of labels, each only
specifying a name (no model). In my initModel() I am creating a
CompoundPropertyModel around super.initModel(). I was expecting it to
pull these properties from the model object of my ProductPanel.
public class ProductPanel extends GenericPanel<Product> {
public ProductPanel(final String id) {
add(new Label("name"));
add(new Label("condition"));
}
protected IModel<?> initModel() {
return CompoundPropertyModel.of(super.initModel());
}
}
But I get this error: org.apache.wicket.WicketRuntimeException: No get
method defined for class: class com.cellcycleusa.domain.Post expression:
name.
Seems that it's trying to access the Post object from the DataView to
pull the property from, not the model object of the ProductPanel itself.
Now the really funny part is that if I just add this to ProductPanel,
everything works fine:
protected void onBeforeRender() {
getModel();
super.onBeforeRender();
}
Or if I specify the model objects for the labels within ProductPanel
like this:
new Label("name", new ComponentPropertyModel<String>("name"))
That works as well.
What am I doing wrong?
