Re: Populating form Elements from another object.

Again I haven't used Niall's classes but I'd hazard a guess that as  
they extend DynaBean that you use the map like interface for accessing  
these properties. In fact I imagine you can cast them as a DynaBean  
like you can with the DynaActionForms

DynaBean myForm = (DynaBean) form;
String foo = myForm.get("foo").toString();

Yup, thats it - plus dynamic="true"

 <form-bean name="fooForm1"
type="lib.framework.struts.LazyValidatorActionForm" dynamic="true" />
 <form-bean name="fooForm2"
type="lib.framework.struts.LazyValidatorActionForm" dynamic="true" />
 <form-bean name="fooForm3"
type="lib.framework.struts.LazyValidatorActionForm" dynamic="true" />
 <form-bean name="fooForm4"
type="lib.framework.struts.LazyValidatorActionForm" dynamic="true" />
Oh, I noticed an error in LazyValidatorForm, its declared as  
"abstract" -
which it shouldn't be - I don't use it directly, I use
LazyValidatorActionForm which extends it.

I haven't seen the code but if what i understand of what Niall has  
been
saying you'd  use them instead of DynaActionForm.

<form-bean name="fooForm" type="com.ilovesparrows.struts.NiallsForm"  
/>

of course you'll need to call the package and class name to something
appropriate.

Hi,

   I saw your code. I have one doubt. How do you plugin your own
DynaBean implementation into the struts framework.

Hi,

     I have a requirement where i need to populate the values of a
form from another object, and then again transform the contents of
the form back to the object once the form is submitted. i.e Say,
when i click a button, i do some functionalities and have a
Properties object as an output. The keys in the Properties object
are not static. These values need to be shown in a form. As the  
keys
retrieved for the current operation is not known, i cant define  
the
values in the struts-config.xml for the dynaactionclass.

      Is it possible to extend the dynaactionclass, and during its
init or something, iterate the properties object and populate the
form.  Are there any other way of doing it.
Thanks
Shanmugam PL
