Models and panel updates
Hello all, I have been trying to resolve this issue. I have a panel
that shows a product info.
public class ProductDetails extends Panel {
public ProductDetails(String id, final Product product) {
super(id);
setOutputMarkupId(true);
this.setCurrentProduct(product);
add(new Label("id"));
add(new Label("codProduct"));
add(new AjaxLink<String>("save") {
@Override
public void onClick(AjaxRequestTarget target) {
System.out.println("saving product .... ");
}
});
}
public void setCurrentProduct(Product product) {
setDefaultModel(new CompoundPropertyModel<Product>(product));
}
}
when ever I click a link to update the product panel using ajax link,
I get the correct info displayed. However, I need to be able to edit
the labels in the panel. So I used :
add(new AjaxEditableLabel<String>("codProduct"));
I get this:
WicketMessage: No get method defined for class: class
rentals.entities.Product expression: label
In a previous thread, I was advised to use CompoundPropertyModel, and
I think it's easier, but why I am getting this ?

If you look at the source code for AjaxEditableLabel you could've seen
that it is not suited for CompoundPropertyModel usage. Because the
editor requires two components: a label and an input box, which are
both created with "label" ,resp. "editor" component identifiers, which
both bind to the default model (in your case: none), they will use
their component id's to look up their model bindings. This is easily
solvable by providing an explicit propertymodel to the AEL.
The following should work:
add(new AEL("codProduct", new PropertyModel<String>(getDefaultModel(),
"codProduct")));

so what should I use in this case?
can you give me an example, to update the panel and have ajax fields ?

Hi!
I would dis-advice you using compoundpropertymodel. Dropping it will
make everything more explicit and clear all your problems. Using
compoundpropertymodel you will get all kinds of surprises.. sometimes,
and spend lot of extra time resolving.

Re: Models and panel updates
Posted by Arjun Dhar <dh...@yahoo.com>.
Help me understand this,.... An AjaxBased components send update events as
they change!
That means except for SAVE having to save the data in one ajax request you
dont need the other fields being AJAX based. See onAfterRender() this is
able to give you the updated value as it happens:
public ProductPanel(String id) {
super(id);
setOutputMarkupId(true);
add(new Label("id"));
//add(new Label("cost"));
AjaxEditableLabel costLabel = new AjaxEditableLabel<String>("cost") {
@Override
public void onEdit(AjaxRequestTarget target) {
super.onEdit(target); //Does the whole convert to text box magic
Float cost = (Float)getDefaultModel().getObject();
log.info("[ProductPanel.AjaxEditableLabel.onEdit] cost prior to update =
" + cost);
}
@Override
public void onAfterRender() {
super.onAfterRender();
Float cost = (Float)getDefaultModel().getObject();
log.info("[ProductPanel.AjaxEditableLabel.onAfterRender] cost after
update = " + cost);
}
};
add(costLabel); //Updatable label
add(new AjaxLink<String>("save") { //But are we saving for?? All the other
fields are already AJAX based and sending updates!
@Override
public void onClick(AjaxRequestTarget target) {
log.info("saving product .... ");
//Line below gives -- WicketMessage: No get method defined for class:
class arjun.learning.data.Product expression: save
Product model = (Product)getDefaultModel().getObject(); //Will give
ERROR :(
log.info("[ProductPanel.AjaxLink.onClick] cost = " + model.getCost());
}
});
}
..The model is updated on changing the value of the cost field itself.
Also, its perfectly understandable why the Model is not marshaling
(becausethere are fields other than the domain object , and obviously the
"CompoundPropertyModel" doesn't know the difference between a Domain Model
field and a field added to the panel for display. They are all part of the
model, some of which not in your domain model.
..So where am I missing the point? :)

Hi,
>I think you mean that I need to use the PanelDetails class as a model,
and create all the properties in it.
it's not necessary to copy all properties to the panel. A
CompoundPropertyModel doesn't care where it gets its properties from. As
I have written, the following should work:
setDefaultModel(new CompoundPropertyModel<Product>(product));
The example just shows that AjaxEditableLabels work fine with
CompoundPropertyModels.

Re: Models and panel updates
Posted by Mansour Al Akeel <ma...@gmail.com>.
Sven, thank you.
I had a look at the Ajax example. I think you mean that I need to use
the PanelDetails class as a model, and create all the properties in
it. This is very verbose as the Product class contains many fields
that I need to edit, and adding getters/setters to the PanelDetails
class will make it big, and the code is repeated.
Based on the example, my class should be:
public class ProductDetails extends Panel {
@EJB
private ProductServicesLocal productServices;
private Product product;
public ProductDetails(String id, Product product) {
super(id);
setOutputMarkupId(true);
this.setCurrentProduct(product);
add(new Label("id"));
add(new AjaxEditableLabel<String>("codProduct"));
add(new AjaxLink<String>("save") {
@Override
public void onClick(AjaxRequestTarget target) {
System.out.println("saving product .... ");
}
});
}
public void setCurrentProduct(Product product) {
this.product = product;
setDefaultModel(new CompoundPropertyModel<ProductDetails>(this));
}
public void setCodProduct(String codProduct) {
this.product.setCodProduct(codProduct);
}
public String getCodProduct() {
return this.product.getCodProduct();
}
}
This brings up a question, what is the best way to wrap domain objects
in a Model for easy CRUD and with a minimum amount of coding, and
reusing the component (ie, without having to recreate the object) ?

Hi,
please see EditableLabelPage.java in wicket-examples for AjaxEditableLabels working with a CompoundPropertyModel.
>Why would the reference be outdated, since ProperyModel is considered dynamic module ?
PropertyModel is dynamic in the property it provides, but it is hard-wired on the object you give to its constructor.
Hope this helps

Re: Models and panel updates
Posted by Mansour Al Akeel <ma...@gmail.com>.
Sven,
thank you, but it worked when using this ?
add(new Label("codProduct"));
Is there an easy way to update the default model And the
AjaxEditableLabel in the similar fasion? Nice to have an example.
Why would the reference be outdated, since ProperyModel is considered
dynamic module ?
Thank you.

Re: Models and panel updates
Posted by Sven Meier <sv...@meiers.net>.
Hi,
it's the "outdated reference" problem (as often when something goes
wrong with models):
new PropertyModel<String>(getDefaultModel(), "codProduct"))
Note that you're putting the current default model into another model.
Later on you change the default model:
setDefaultModel(new CompoundPropertyModel<Product>(product))
How should your PropertyModel be aware of this change?
BTW Martijn's statement is incorrect:
>If you look at the source code for AjaxEditableLabel you could've seen
>that it is not suited for CompoundPropertyModel usage.
AjaxEditableLabel is very well capable of working with
CompoundPropertyModels, see AjaxEditableLabel#getParentModel().

Re: Models and panel updates
Posted by Mansour Al Akeel <ma...@gmail.com>.
Hello Martrin, and Ernesto,
it's still not working. I have this ProductPanel to be updated and
(possibly edited). It shows the product info when an item is clicked.
Here's the code for the Product Panel:
public class ProductDetails extends Panel {
@EJB
private ProductServicesLocal productServices;
public ProductDetails(String id, final Product product) {
super(id);
setOutputMarkupId(true);
this.setCurrentProduct(product);
add(new Label("id"));
add(new AjaxEditableLabel<String>("codProduct",
new PropertyModel<String>(getDefaultModel(), "codProduct")));
add(new Label("tpVat"));
add(new AjaxLink<String>("save") {
@Override
public void onClick(AjaxRequestTarget target) {
System.out.println("saving product .... ");
}
});
}
public void setCurrentProduct(Product product) {
setDefaultModel(new CompoundPropertyModel<Product>(product));
}
}
And here's the code for the item to update the 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(product.getId());
}
};
item.add(link);
The problem with this code, is the Editable Label doesn't update with
the rest of the labels. I mean if I click on an item, it shows me the
results for the corresponding product in the Labels, but not in the
AjaxEditableLabel.

you need to add the updated panel into target:
target.addComponent(panelToBeUpdated);

Do you mean update the whole panel when you edit the "codProduct"?

I just tried it. It doesn't update the panel. Here's the full code:
public class ProductDetails extends Panel {
@EJB
private ProductServicesLocal productServices;
public ProductDetails(String id, final Product product) {
super(id);
setOutputMarkupId(true);
this.setCurrentProduct(product);
add(new Label("id"));
add(new AjaxEditableLabel<String>("codProduct",
new PropertyModel<String>((Product)getDefaultModelObject(), "codProduct")));
add(new AjaxLink<String>("save") {
@Override
public void onClick(AjaxRequestTarget target) {
System.out.println("saving product .... ");
}
});
}
public void setCurrentProduct(Product product) {
setDefaultModel(new CompoundPropertyModel<Product>(product));
}

can you try
add(new AjaxEditableLabel<String>("codProduct", new
