hi
for this create 2 int variables <b>act</b> and a <b>counter</b>
//@@begin others
  static int act,counter=0;
  //@@end
<b>in Doinit set act to 0.</b>
public void wdDoInit()
    //@@begin wdDoInit()
    act=0;
    //@@end
<b>create an action(onActionCreate_Element) and assign it to the button ui element</b>
public void onActionCreate_Element(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionCreate_Element(ServerEvent)
    act = 1;
    //@@end
<b>in wdDoModifyView</b>
public static void wdDoModifyView(IPrivateDynamicView wdThis, IPrivateDynamicView.IContextNode wdContext, com.sap.tc.webdynpro.progmodel.api.IWDView view, boolean firstTime)
    //@@begin wdDoModifyView
    if( act== 1)
         IWDTransparentContainer con= (IWDTransparentContainer)view.getElement("RootUIElementContainer");
         IWDInputField input = (IWDInputField)view.createElement(IWDInputField.class,"input1"+counter);
         IWDAttributeInfo test = wdContext.getNodeInfo().addAttribute("name"+counter,"ddic:com.sap.dictionary.string");
         input.bindValue(test);
         input.setVisible(WDVisibility.VISIBLE);
         counter++;
         con.addChild(input);
                act = 0;
    //@@end
