Re: Accessing Page components
Just declare them final, should work just fine, but with consequences (you
wont be able to re-reference them in a future).

Is simple possibility to access page components in anonymous onClick
method like in code below ?
public class NewLinkPanel extends Panel {
public NewLinkPanel(String id) {
super(id);
TextField name = new TextField(name);
TextField address = new TextField(address);
add(name);
add(address);
add(new AjaxLink(ok){
public void onClick(AjaxRequestTarget target) {
// how to get name and address values ?
System.out.println(ok);

Thanks in advance.

However, I never do it like this. I always use PropertyModels() to 'map' my
TextFields to properties of my object. This way your code in the onClick()
method uses that just the object properties. (Note that the AjaxSubmitLink
has no onClick(), but a onSubmit()...)
Pieter
Thanks Pieter. I got working this like below:
public class NewLinkPanel extends Panel {
public NewLinkPanel(String id) {
super(id);
add(new LinkForm(linkform));
}
}
class LinkForm extends Form {
public LinkForm(String id) {
super(id);
Link link = new Link();
this.setModel(new Model(link));
add(new TextField(name, new PropertyModel(link, name)));
add(new TextField(address,new PropertyModel(link,
address)));
add(new AjaxSubmitLink(ok){
@Override
protected void onSubmit(AjaxRequestTarget target, Form
form) {}
});
}
@Override
protected void onSubmit() {
Link l = (Link)this.getModelObject();
new LinkDAO().save(l);
}
}
Now i want to update (refresh) my another panel with list of links on my page :D
That will be a problem for me now. I'm beginner

Re: Accessing Page components
There are several ways how you can do this...
To encourage losely coupled components folowing is in my opinion the best
solution..
Work with a callback mechanism. let's say you define a callback interface
SaveCallback with a method onSaved(AjaxRequestTarget target).
The component that uses you panel/form, can pass such a callback to define
de 'code' that needs to be executedn once the Link is saved.
class MyPage {
public MyPage() {
//construct panels
final Panel otherPanel = new .
otherPanel.setOutputMarkupId(true); //make it possible to refresh this
panel via ajax
add(otherPanel);
add(new NewLinkPanel(newLinkPanel,new SaveCallback() {
onSaved(AjaxRequestTarget target) {
target.addComponent(otherPanel);//refresh other panel
}
});
}
}

Re: Accessing Page components
Use the onSubmit(AjaxRequestTarget target) of your AjaxSubmitLink instead of
your form.
(Note that if you make use of FeedbackPanel, youd should also override the
onError() method of that ajaxlink to 'refresh' your feedback panel)

Accessing Page components
Is simple possibility to access page components in anonymous onClick
method like in code below ?
public class NewLinkPanel extends Panel {
public NewLinkPanel(String id) {
super(id);
TextField name = new TextField(name);
TextField address = new TextField(address);
add(name);
add(address);
add(new AjaxLink(ok){
public void onClick(AjaxRequestTarget target) {
// how to get name and address values ?
System.out.println(ok);
}
});
}
}
Thanks in advance.

Re: Accessing Page components
Place your textfields in a Form. Replace your AjaxLink() by a AjaxSubmitLink
(and place that link also in the form)
then, you should be able to get the values by name.getDefaultModelObject() I
think...
However, I never do it like this. I always use PropertyModels() to 'map' my
TextFields to properties of my object. This way your code in the onClick()
method uses that just the object properties. (Note that the AjaxSubmitLink
has no onClick(), but a onSubmit()...)

Re: Accessing Page components
If you want to access them from a call you need to declare them final
final TextField name = new TextField(name);
But i' m missing a Model that should receive the values from the form
components?
Normally, with wicket you do not access the FormComponets to get the values but
let Wicket handle the conversion and validation.
Or do you use a CompoundPropertyModel (not shown in the code) ?
