Thanks anyway

My bad. I didn't read your mail through; only saw the top portion. In your setupUserAction, after you prepopulate the form, set it as a request
attribute:
request.setAttribute("userForm",userForm);from SetUpUserAction.execute()
DynaActionForm userForm = (DynaActionForm)form;
userForm.set("userName",user.getUserName());
userForm.set("password",user.getPassword());
userForm.set("fullName",user.getFullName());
userForm.set("email",user.getEmail());
userForm.set("status",new Integer(1));
forward = mapping.findForward("Success");
return forward;
It works when the form is in session scope because that will make the whole session deal with one form instance.

http://jakarta.apache.org/struts/userGuide/building_controller.html#dyna_action_form_classesAs far as I can tell, there really isn't any support for prepopulating a DynaActionForm. The ff is from
"DynaActionForms are not a drop-in replacement for ActionForms. If you need
to access ActionForm properties in your Action, you will need to use the
map-style accessor, like myForm.get("name"). If you actively use the
ActionForm object in your Action, then you may want to use conventional
ActionForms instead.
"DynaActionForms cannot be instantiated using a no-argument constructor. In order to simulate the extra properties, there is a lot of machinery involved in their construction. You must rely on Struts to instantiate a DynaActionForm for you, via the ActionMapping."
What I did was copy the code that RequestUtils uses to instantiate a DynaActionForm, and put it in a method that I can call like this: DynaActionForm dynaForm = createDynaActionForm("formName", mapping.getModuleConfig());
/**
* <p>Create the [EMAIL PROTECTED] DynaActionForm} instance identified by the
given
* formName.</p>
* * @param formName the name used to identify the form
* @param moduleConfig the configuration for the current module
* @return the DynaActionForm identified by formName
*/
public static DynaActionForm createDynaActionForm(
String formName,
ModuleConfig moduleConfig) {
DynaActionForm dynaForm;
try {
// the code here is based on [copied from? :) ]
// RequestUtils.createActionForm()
FormBeanConfig formBeanConfig =
moduleConfig.findFormBeanConfig(formName);
DynaActionFormClass dynaClass = DynaActionFormClass.createDynaActionFormClass( formBeanConfig);
dynaForm = (DynaActionForm) dynaClass.newInstance();
if (logger.isTraceEnabled()) { logger.trace("inside findDynaActionForm() where dynaForm=" + dynaForm + " and formBeanConfig=" + formBeanConfig); }
initializeDynaForm(formName, dynaForm, moduleConfig); } catch (Exception e) { logger.error("Exception [" + e + "," + e.getMessage() + "]", e); // TODO what to do if we get an error initializing the form? // -> right now we're just returning null dynaForm = null; } return dynaForm; }

FormBeanConfig config = moduleConfig.findFormBeanConfig(name); if (config == null) { return; } FormPropertyConfig props[] = config.findFormPropertyConfigs(); for (int i = 0; i < props.length; i++) { dynaForm.set(props[i].getName(), props[i].initial()); } }

I am newbie to Struts and have a problem with populating DynaActionForm. I have two actions: one to set up userForm and one to process it. 1st one is suposed to grab user info and populate the form. The second one updates user info after the form is submitted. The problem is that the from is not populated. Moreover changing the scope to "session" in action "/user/setUp" results in form being populated with appropriate data. What am I doing wrong in here?redirect="true"/>
