How to clear the form fields which are not rendered

Question

I have a creation form. There is a document_type list set up as a partial triger. When user change the document type, only the filed related to that document type will be rendered. This caused a problem when we need to clear the form . The input in the field which is not render won't be cleared when reset button is pressed. Can anybody give a sugestion on how to handle this?
I tried to use the following function to clear the fields. It does not work since it get the list value before the list value change and clear the fields after the new field rendered.
public void clear_action(ValueChangeEvent valueChangeEvent) {
// Add event code here...
System.out.println("test1");
String coutcase = null;
if(EL.get("#{bindings.Proxy.inputValue}") != null){
coutcase = EL.get("#{bindings.Proxy.inputValue}").toString();
System.out.println(coutcase);
AttributeBinding a11= (AttributeBinding)getBindings().getControlBinding("INT_FNAM");
AttributeBinding a12 = (AttributeBinding)getBindings().getControlBinding("INT_LNAM");

AttributeBinding a26 = (AttributeBinding)getBindings().getControlBinding("DEFEN");

Hi,
The easiest way to modify the screens in the Std transactions using ITS is to modify the ITS templates corresponding to that transaction.
E.g In you case,there will be a ITS service corresponding to the ESS transaction.This ITS service will have  number of HTML templates which will actually correspond to the diffrent screens in the Trascn.What you need to do is find out the HTML template in the ITS service which corresponds to the screen(which you want to modify) in the STd transacn.To do this ,the easiest way is to right click on that Web page and say VIEW SOURCE.It will show you a HTML code with the ITS service name and the template which is being used for that particular screen.
So after you find out the correct HTML template to be modified,you can simply hide the fields by putting the HTML code lines in between the symbols
