What's wrong? [prepopulating a form...]

[lk <ce...@email.it>]

Hi,

I'm trying to prepopulate a form for editing it and I can't understand 
what's wrong.

 From a list of objects I want to edit one. I have an action for that:

<action	path="/polizza_mod"
	type="mypackage.PolizzaFormModAction"
	name="polizza_newForm"               	
	scope="request"
	input="/gestione/polizza_mod.jsp"				
	validate="false">
	<forward name="OK" path="/gestione/polizza_mod.jsp"/> 
</action>

^^^^^^^^^^^^^^^^^
polizza_newForm is a DynaActionForm defined in the struts-config.xml

^^^^^^^^^^^^^^^^^
The action is:

import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.validator.DynaValidatorForm;

public class PolizzaFormModAction extends Action
{
	public boolean DEBUG = true;	
	
	public ActionForward execute( 	ActionMapping mapping,
					ActionForm form,								HttpServletRequest request,
					HttpServletResponse response)
					throws Exception
	{
	HttpSession session = request.getSession();				

	// Here I create the bean
	PolizzaBean pb = new PolizzaBean(getDataSource(request, 
Parameters.NOME_DATA_SOURCE));
	PolizzaDTO p = pb.getPolizza(request.getParameter("id"));

	// SAVE THE OBJECT "polizza" in the session
	session.setAttribute("polizza", p);
	
	ServletContext sc = this.getServlet().getServletContext();
	xferToForm(p,form,sc);
	session.setAttribute("polizzaForm", form);
	return (mapping.findForward("OK"));			

	}
	
	/**
	 * transfer bean data to form
	 */
	private void xferToForm(PolizzaDTO polizza, ActionForm form, 
ServletContext sc)
	{
		((DynaValidatorForm)form).set("nome",polizza.getNome());
	}	
}

^^^^^^^^^^^^^^^^^

Everything works fine but the form
"/gestione/polizza_mod.jsp"
is empty?

Why???

If I try to print on that form the bean polizza_newForm the properties 
are correct:

<c:out value="${polizza_newForm}" />
gives:

DynaActionForm[dynaClass=polizza_newForm,nome=test]

My form is:
<html:form action="/polizza_new_preview.do">
	<html:text
		name="polizza_newForm"
		property="nome"
		size="25"
		maxlength="25"
		value= ""
	/>
<html:submit value="Conferma" styleClass="bottone" />
<html:button value="Elimina" property="Elimina" styleClass="bottone" 
/>		<html:reset value="Annulla" styleClass="bottone" />		
</html:form>	

Thanks

LuKe

Gotcha!!!!

Oh poor man :-)

The problem was in the form:

I used the attribute value="" for the html:text tag from an old form!!!!
