I see, sorry I wasn't paying attention to your constructor.
Try creating your components with something like this...
...
...
street = createHtmlInputText("street");
number = createHtmlInputText("number");
town = createHtmlInputText("town");
postCode = createHtmlInputText("postCode");
command = createHtmlCommandButton("command");
...
...
}
protected HtmlInputText createHtmlInputText(String id) {
Application application = FacesContext.getCurrentInstance
().getApplication();
HtmlInputText intput =
(HtmlInputText)application.createComponent
(HtmlInputText.COMPONENT_TYPE);
input.setId(id);
return input;
}
protected HtmlInputText createHtmlCommandButton(String id) {
Application application = FacesContext.getCurrentInstance
().getApplication();
...
...
The problem is in how you are creating new components. It isn't
enough just to do new HtmlXXX(), you must create them with the
createComponent method. There's a few things going on under the
covers with respect to how JSF deals with components. You might also
think about getting a good book or referencing a tutorial while
building your app. There's a lot more to JSF than meets the eye.

Assuming you are using JSP, how are using this on your page? With
your own taglib or binding to an existing instance? If you are
simply binding a standard HtmlPanelGrid and then declaring child
components, you will need to bind any nested components as well.

Hello all,
Starting to learn JSF, i tried to create my custom UI component.
Because
it will be made of several fields and button, i decided to extends
HTMLPanelGrid. The constructor creates the various components
part of
the Panel. After getting "funny" errors in console, i worked on a
step
by step and noticed in restore view, myfaces does inject childs
in my
component (so the number of child is double: those created at
intanciation of my component and those saved from previous
instance and
injected as part of restore view).
My question is, considering the way i do it for now (which is
bad ;) ),
what is the best way to avoid this restore view problem. How can my
component know if it is in a state where it need to create itself
it's
children or in a state where the controller will restore the
children
tree itself?
Thank for help.
public class HTMLAddressComponent extends HtmlPanelGrid implements
NamingContainer {
.....
public HTMLAddressComponent(){
street = new HtmlInputText();
number = new HtmlInputText();
town = new HtmlInputText();
postCode = new HtmlInputText();
command = new HtmlCommandButton();
command.setValue("enable/disable");
street.setId("street");
number.setId("number");
town.setId("town");
postCode.setId("postCode");
command.setId("command");
List childs = getChildren();
HtmlPanelGroup group = new HtmlPanelGroup();
List l = group.getChildren();
l.add(getText("Street: "));
l.add(street);
l.add(getText("Number: "));
l.add(number);
childs.add(group);
group = new HtmlPanelGroup();
l = group.getChildren();
l.add(getText("postcode: "));
l.add(postCode);
l.add(getText("Town: "));
l.add(town);
childs.add(group);
childs.add(command);
}
private UIComponent getText(String value){
HtmlOutputText text = new HtmlOutputText();
text.setValue(value);
return text;
}
