dynaform populate

  Can anyone help me on this?
  I am trying to pass a populated DynaActionForm to a JSP file and I can't
figure out how can I populate the form...

  I have the following sequence:

  - form A (name : gotoUserPrefsForm, id : String - user id)
  - action ViewUserPreferences (uses form A)
  - form B (name : userPrefsForm, severall attributes)


  ViewUserPreferences {

    /** @param form this is form A. */
    ... execute(..., form, ...) {

        int id = FormUtils.getIntValue(form, "id");

        UserPreferences prefs = service.getUserPreferences("id");

        // here starts the problem!!!
        // gets the form bean configuration
        FormBeanConfig fc = config.findFormBeanConfig(mapping.getName());

        // this is supposed to be form B
        DynaValidatorForm dynaForm = // how do I create a new instance with
the FormBeanConfig?...


        dynaForm.set("background", prefs.getBackground());

        request.setAttribute("userPrefsForm", dynaForm);

    }

  } 


  Any ideas?

Hi again,

i have this for one property:

<html:text name="bean" property="foo"/><html:errors property="foo"/>

on submit, the "normal" validation-flow runs...

you have an html!!!-formular (the generated one which you can see via
browser, and its source),
named like your formbean-name in struts-config.xml
you only got the "filled" textfield via a "normal" javaBean

after submitting, in your corresponding actionClass you

get an ActionForm-object, (base of DynaValidatorForm)
with these values...(came from html-form)



please look also here,
there you see, that formBeans are not! model-components of
MVC-(web).apps.
http://jakarta.apache.org/struts/userGuide/building_model.html
section (2.3)

greetings
Matthias

  I didn't knew html:text had a name attribute :)
  I usually use

<html:text property="background" styleClass="field_required"/> (I
supposed, in this case, the name attribute is the form-bean name defined
on the struts config file)...

  One more question, if you have validation errors (after submitting the
form), you still have to pass the form properties to your helperBean or
the JSP page automatically presents the previous sent values (just like
doing a back on the browser)?

Thank you again,

Hi Pedro,

the properties are!!! important!!!



i do the following in an action:

request.setAttribute("helperBean",myValueObject);

return mapping.findForward("updateFormularPage");



and have something like that in
the forwarded jsp 

<struts-html:form action="/myActionPath">
<struts-html:text name="helperBean" property="foo"/>

...

</struts-html:form>


it works fine!


Regards, Matthias

What you are telling me is that if I store a bean with the same name as
the form, the html tag lib will interpret it as being the form, right?

What you are telling me is that if I store a bean with the same name as the
form, the html tag lib will interpret it as being the form, right?

RE: dynaform populate

Posted by Matthias Wessendorf <ma...@matthias-wessendorf.de>.
Hi Pedro,

with:

FormBeanConfig fbc = new FormBeanConfig();
fbc.setName("myForm");
DynaActionFormClass dafc =
DynaActionFormClass.createDynaActionFormClass(fbc);
DynaActionForm formBean = (DynaActionForm) dafc.newInstance();
formBean.set("property", businessObject.getProperty());
request.setAttribute("userPrefsForm",formBean);
//End

you can create a dynaBean.
i had the problem long time ago two.

why are willing to use dynaBeans for populating a JSP-Form-Page?

i use "ValueObjects" or "HelperBeans" instead, which i store in
request and with there properties the formfilds get filled to! 

look
http://rollerjm.free.fr/images/ClassStruts1_1.gif
an nice diagramm :-)

greetings 
Matthias

  Can anyone help me on this?
  I am trying to pass a populated DynaActionForm to a JSP file and I

  I have the following sequence:
