html:form question

[Scott Purcell <sp...@vertisinc.com>]

Hello,
 
I have a login that I call and displays its initial presentation. I am using the <html:form action="login.do"> line for when I submit its values.
 
But I want to put in some default values into the initial presentation. So upon reading about
<html:form> it looks like I could use the following:
<html:form action="login.do" name="loginBean" type="com.ddi.dealer.bean.LoginForm">
 
Because in my struts-config.xml I have the following two sections
 
  <form-beans>
    <form-bean name="loginBean" type="com.ddi.dealer.bean.LoginForm" />
  </form-beans>
 
  <action
    path="/login"
    input="/jsp/login.jsp"
    type="com.ddi.dealer.action.LoginAction"
    name="loginBean"
    scope="request"
    validate="true">
    <forward name="Success" path="/jsp/welcome.jsp" />
    <forward name="Failure" path="/jsp/login.jsp" />
  </action>
 
So I was hoping that that form line would call, create new loginBean and show the data in my initial feed.
 
The submitting is good, It was just something I am not understanding.
 
Anyone know why that does not work?
 
Thanks,
Scott

I think the name and type attributes to html:form were deprecated at 1.1 
and now no longer exist.

I'm not sure I know exactly what you are trying to do. But it sounds 
like you are trying to do what I would do in a standard setup 
Action/form processing Action pairing. I would have an Action that 
switches on the action mapping's "parameter" attribute. Two action 
mappings, same Action. One mapping would have parameter="viewLogin", the 
other parameter="doLogin". Both would name the form bean to 
instantiate/use, but the view mapping has validation turned off while 
the do mapping has validation turned on. Struts has various 
dispatch-type Actions that do this stuff more automatically but 
switching on a parameter works for me.

In the Action, if I'm processing "viewLogin", and I want default values, 
I invoke a populateForm method, passing 1) the form 2) a value object 
(presumably obtained from the model) used to set initial values.

Hope that helps.

Erik
