Building custom components in jsf 1.2

Question

HI all
i am having custom component which has one text field and button together which is extended from a panelgroup component and adding text field and button and child component to this.
in jsf1.1 i am not getting any error, but jsf 1.2 i am getting arrayoutofbounds exception in processrestorestate.
when printing the log in jsf1.2 uicomponentbase we can see that after text and button fields are rendered again textfield is rendered.and kid of panel is 4. can you suggest how building the above custom component.
kid.........4 facet count.0 family javax.faces.Panel
stateStruct.........[Ljava.lang.Object;@c0f87elength.......2
childstate.....[Ljava.lang.Object;@fa302clength...2
Child Count4
kids....4
kid.........0 facet count.0 family javax.faces.Input
stateStruct.........[Ljava.lang.Object;@170d9d4length.......2
kid.........0 facet count.0 family javax.faces.Command
stateStruct.........[Ljava.lang.Object;@1ed1c32length.......2
kid.........0 facet count.0 family javax.faces.Input

hi
is there a problem in rendering code in have given for the component. please tell me what is wrong in the code.
my component code is
package components;
import javax.faces.component.html.HtmlInputText;
import javax.faces.component.html.HtmlCommandButton;
import javax.faces.component.html.HtmlPanelGroup;
public class CGLookup extends HtmlPanelGroup
    private HtmlInputText text1;
    private HtmlCommandButton btn1;
    private String key,valueText,id;
    private String width,valueChangeListener;
    private int maxLength;
    private boolean required;
    private static Class valueChangeListenerArgs[]= (new Class[] {javax.faces.event.ValueChangeEvent.class});
    public CGLookup()
        super();
        //this.setSeparator("");
        this.setStyle("width:198px;");
        text1= new HtmlInputText();
        text1.setStyle("width: 150px;");
        btn1 = new HtmlCommandButton();
       // btn1.setMini(true);
       // btn1.setStyle("width: 7px; height: 20px");
        btn1.setLabel("?");
        this.getChildren().add(text1);
        this.getChildren().add(btn1);
    public void setId(String id)
        super.setId(id);
        text1.setId(id+"_txt");
        btn1.setId(id+"_btn");
    public String getText()
        if(text1.getValue() !=null)
            return text1.getValue().toString().toUpperCase();
        return null;
    public void setText(String value)
        if(value!=null)
            text1.setValue(value.toUpperCase());
        else
            text1.setValue(null);
    public int getMaxLength()
        return text1.getMaxlength();
    public void setMaxLength(int value)
        text1.setMaxlength(value);
    public void setRequired(boolean value)
        text1.setRequired(value);
    public void setDisabled(boolean value)
            text1.setDisabled(value);
            btn1.setDisabled(value);
    public String getValueText()
        return valueText;
    public void setValueText(String value)
        valueText = value;
    public String getKey()
        return key;
    public void setKey(String value)
        key = value;
    public String getWidth()
        return width;
    public void setWidth(String value)
        width = value;  
        if (width != null)
            resize();
    public void resize()
        this.setStyle("width:"+width);
        int index = width.indexOf("px");
        String temp = width.substring(0, index);
        int _width = Integer.parseInt(temp);
        _width = _width -48;
        HtmlInputText t1 = (HtmlInputText) this.getChildren().get(0);
        t1.setStyle("width:"+ String.valueOf(_width)+"px");

}the component type CGLookuptype refers to first code. in jsf 1.2 UIComponentTag says it is deprecated. what should i use instead of it.
