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;
}
