At this point I would override/debug method updateModel() inside 
AddressPanel to see if model's object is modified by this method .

Just my 2 cents...

Yes, I think you are doing it the Wicket way, but your snippet and
mine should work. Do you modify components' model somewhere else?

No, I don't think so. The page to which the component is added is constructed 
as follows:

CompoundPropertyModelHomePage  model = new 
CompoundPropertyModelHomePage(this);
FormHomePage  form = new FormHomePage(form, model);
form.add(new TextFieldString(person.firstname));
form.add(new AdresPanel(person.adres));

No other code modifies the model.


Which model do you get if you call getDefaultModel() inside oninitialize?

The result of getDefaultModel() is an instance of 
CompoundPropertyModel$AttachedCompoundPropertyModel, with owner set to the 
AdresPanel and with target set to a CompoundPropertyModel which in turn has 
target HomePage.

I noticed that upon initializing the model is set correctly. However when 
inspecting the model in onBeforeRender() during the submit request the target 
of the model of the AddressPanel.street model is set to HomePage.


Thanks for your reply. I've tried it but it still gave the same error.

However I also tried the following modified version of your idea:

In AddressPanel.java:

@Override
protected void onInitialize() {
super.onInitialize();
 Object o = getDefaultModelObject();

 setDefaultModel(new CompoundPropertyModel(getDefaultModelObject()));
}

With the above code I can now load the page, also the

getDefaultModelObject() returns the correct Address instance. Unfortunately
upon submitting the form I get the same exception again (No get method
defined for class: class foo.HomePage expression: street).

By the way: am I doing things the Wicket way? Is this how you would reuse

parts of a form in Wicket?

Bob

RE: CompoundPropertyModel and FormComponent

2012-01-18 Thread Schlärmann , Bob
Thanks for your response. After some more debugging I've found the cause and 
also found a solution.

The cause is that models of intermediate components, such as the Panel in my 
case, are never initialized if they do not already have a model. 

The parent's model is looked up in Component.initModel(), however this method 
uses a special method for getting the model of the parent that does not 
initialize the parent's model if it is not already initialized. The behaviour 
is intentional as there is a comment on this line:

// Get model
// Don't call the getModel() that could initialize many inbetween
// completely useless models.
// IModel model = current.getModel();
IModel? model = current.getModelImpl();

In my case I think this intermediate the inbetween model should get 
initialized. 

The workaround is to initialize the model in onBeforeRender(), before calling 
super.onBeforeRender(), and let the Panel implement the IFormVisitorParticipant 
interface. Then in IFormVisitorParticipant.processChildren() initialize the 
model again (by just calling getDefaultModel()). This last trick is needed in 
order to get the model initialized before it's children are submitted.

The complete class is as follows:

public class AddressPanel extends Panel implements IFormVisitorParticipant {
public AddressPanel(String id) {
super(id);

add(new TextFieldString(street));
}

protected IModel? initModel() {
IModel? model = super.initModel();

return new CompoundPropertyModelObject(model);
}

protected void onBeforeRender() {
getDefaultModel(); // getDefaultModel initialized model if not yet 
initialized

   super.onBeforeRender();
}

public boolean processChildren() {
getDefaultModel();

return true;
}
}

In SomePage.class you can bind the panel to an Address property:

Address address; // consists of a single property named street

SomePage() {
   FormSomePage form = new FormSomePage(form, new 
CompoundPropertyModel(this));
   form.add(new AddressPanel(address));
   add(form);
}


This solution seems a bit awkward though so I'm using a constructor with model 
solution in my application.

Best regards,

Bob

CompoundPropertyModel and FormComponent

2012-01-16 Thread Schlärmann , Bob
Hi list,

I've created a reusable form component for editing an address, called 
AddressPanel. It inherits from FormComponent and consists of multiple text 
fields for inputting data, instances of the component get added to a Form 
instance.

How do I use this component together with a CompoundPropertyModel? I'm using 
the following code to add the component to the form:

FormHomePage form = new FormHomePage(form, new 
CompoundPropertyModelHomePage(this)); // HomePage has an instance of Person 
called person
form.add(new TextFieldString(person.firstname));
form.add(new AddressPanel(person.address));

However this gives the following exception: Last cause: No get method defined 
for class: class foo.HomePage expression: street.

street is a text field that is added to the AddressPanel. Is it possible to 
have the street field bound to person.address.street without renaming the 
text field inside AddressPanel? I don't want to rename it since this way I 
can't reuse the component for other entities that have addresses.

Best regards,

Bob

Hi,

I think you need to build a CompoundPropertyModel inside the component 
itself. Override onInitialize method of AddressPanel and try with 
something like this:


@Override
protected void onInitialize() {
super.onInitialize();
setDefaultModel(new CompoundPropertyModel(getDefaultModel()));
}
