Re: load data from db into form

[Adam Hardy]

Hi guys,
could be many whys, but it looks like your form bean is null. have you 
configured your struts-config mapping correctly to reference this form?

You should also cast the form bean into the type of form class you have 
specified, since it is passed into the action as the super class ActionForm.

so now I have it without nested, form definition is now without it.
but still I got

java.lang.IllegalArgumentException: No destination bean specified
    at 
org.apache.commons.beanutils.BeanUtils.copyProperties(BeanUtils.java:220)
    at 
cz.chalu.struts.modules.completeregister.LoadDataAction.execute(LoadDataAction.java:32) 

What is missing? I my action class (execute method) I have:

public ActionForward execute(...){
LoadDataService service = new LoadDataService();
ComplRegisterDTO registerDTO = service.loadUser(request);
BeanUtils.copyProperties(form, registerDTO);
return null;
}
If I understand well, in BeanUtils.copyProperties I copy data from DTO 
into form defined in execute method?
Or something other is wrong?

Thanks

Okay assuming the following..

<form-bean name="registerFull" 
type="org.apache.struts.validator.DynaValidatorForm">
             <form-property name="id" type="java.lang.Integer" />
           <form-property name="fullname" type="java.lang.String" />
            <form-property name="notify" type="java.lang.Integer" />
</form-bean>

..

<html:text property="fullname" />
<html:text property="id" />
<html:text property="notify />
or if you are nesting you bean which in that case i wouldn't (too short).

<form-property name="mybean" 
type="cz.chalu.struts.modules.completeregister.ComplRegisterDTO">

Then assuming that fullname, id, and notify are all properties of 
ComplRegisterDTO.

<html:text property="mybean.fullname" />
<html:text property="mybean.id" />
<html:text property="mybean.notify" />
Cheers Mark
