[newbie] Prepopulating a form

[Johan Wasserman <Jo...@mgxgroup.com>]

Hi,
I need to populate a form from a StateBean (session) before displaying
it.
I cannot find anything to do it when using a FormBean (request) since
the bean is initialised when loading the form and no methods are
available to read the StateBean from the session (or so I think), any
suggestions will be welcome.
 
Thanks in advance.

Create an action which loads the data into your actionform, and  
reference this action instead of the
jsp which displays the form.

Hth,

Hi Johan,

try this...

DynaActionForm yourForm = (DynaActionForm) 	   	 
this.createDynaActionFormFromFormBeanConfig(yourFormName, mapping);

// prepopulate the form
httpSession.setAttribute(yourFormName, yourForm);


protected DynaActionForm 
createDynaActionFormFromFormBeanConfig(String 							name, ActionMapping 
mapping)
   	throws InstantiationException, IllegalAccessException
{
   FormBeanConfig config = (FormBeanConfig) 			  					 
mapping.getApplicationConfig().
					findFormBeanConfig(name);

   DynaActionFormClass dynaClass = DynaActionFormClass.
				createDynaActionFormClass(config);

   return ((DynaActionForm) dynaClass.newInstance());
}

hope this helps.

Marco
