Panel update with Ajax
I have a panel that displays a product info :
public class ProductDetails extends Panel {
private IModel<Product> model;
public ProductDetails(String id, Product product) {
super(id);
setOutputMarkupId(true);
this.setCurrentProduct(product);
add(new Label("id", new PropertyModel<String>(model, "id")));
add(new Label("codProduct", new PropertyModel<String>(this.model,
"codProduct")));
add(new Label("tpVat", new PropertyModel<String>(this.model, "tpVat")));
}
public void setCurrentProduct(Product product) {
this.model = new CompoundPropertyModel<Product>(product);
}
}
I am trying to update it from a link in another panel:
AjaxLink<String> link = new AjaxLink<String>("link") {
{
add(new Label("id", new PropertyModel<String>(model,
"id")));
}
@Override
public void onClick(AjaxRequestTarget target) {
Product product = item.getModelObject();
productDetails.setCurrentProduct(product);
target.addComponent(productDetails);
System.out.println(target.toString());
}
};
item.add(link);
Updates are not shown. I believe the issue is with the Model I am
using (IModel<Product>). However, I don't know the alternative model I
should be using (if it's a model issue).
Product is a JPA entity.
Any ideas ? example ?
thanx

Re: Panel update with Ajax
Posted by "robert.mcguinness" <ro...@gmail.com>.
couple of suggestions:
check the ajax response using the wicket debugger on the client side and see
what it returns
is the panel hidden during page render? maybe setting
setOutputMarkupPlaceholderTag(true) will help. if you are panel swapping
then try using Panel.replaceWith(new Panel())
make sure you detach the model that is tied to the ProductDetails. I try to
pass models across components instead of objects and let Wicket handle the
detaching.

Sven, thank you.
But what about the ajax part.

This one is not working as expected.
Do you have a ling for an example ?

Hi,
always when working with PropertyModel make sure that the properties exists.
In your case it should probably be:
new PropertyModel<String>(this, "model.object.id"))
Note that using the CompoundPropertyModel as suggested earlier is much
easier.

Thank you. I didn't know that wicket will pick the properties without
getters. I thought I have to create a getter for each property before
it's seen. Now the remaining issues:
When I use soemthing like :
add(new Label("id", new PropertyModel<String>(this, "model.id")));
I get an exception:
WicketMessage: No get method defined for class: class
org.apache.wicket.model.CompoundPropertyModel expression: id
Root cause:
org.apache.wicket.WicketRuntimeException: No get method defined for
class: class org.apache.wicket.model.CompoundPropertyModel expression:
id
at org.apache.wicket.util.lang.PropertyResolver.getGetAndSetter(PropertyResolver.java:445)
The second issue is when I use
add(new AjaxEditableLabel<String>("codProduct"));
and then try to update the panel, I get this exception:
WicketMessage: No get method defined for class: class
rentals.entities.Product expression: label
Root cause:
org.apache.wicket.WicketRuntimeException: No get method defined for
class: class rentals.entities.Product expression: label
at org.apache.wicket.util.lang.PropertyResolver.getGetAndSetter(PropertyResolver.java:445)
Any explanation why this is happening ?

PropertyModel doesn't care which object holds the property. In your code
the ProductDetails panel has a property "model", that's all.

This part I don't understand.
I read the wiki about models, but still missing something.

Re: Panel update with Ajax
Posted by Sven Meier <sv...@meiers.net>.
Hi,
a usual error when working with models:
new PropertyModel<String>(model, "id")
Note you're passing around a reference to the initial model. Later
updates of this member will not change any other
reference held anywhere else. You'd have to do it this way instead:
add(new Label("id", new PropertyModel<String>(this, "model.id")));
But since you're using a CompoundPropertyModel already, why not let is
do the heavy lifting?
public class ProductDetails extends Panel {
public ProductDetails(String id, Product product) {
super(id);
setOutputMarkupId(true);
this.setCurrentProduct(product);
add(new Label("id"));
add(new Label("codProduct"));
add(new Label("tpVat"));
}
public void setCurrentProduct(Product product) {
setDefaultModel(new CompoundPropertyModel<Product>(product));
}
}
