Re: Reseting one field on a DynaActionForm to it's initial value?

[Paul Spencer]

My web application has a common form that contains the property 
"SortOrder".  The value of the property is a list of fields used by the 
Action for sorting a list.  I want my Action to reset the value of the 
"SortOrder" to it's initial value, as defined in struts-config.xml.

When a value of the SortOrder is invalid for the Action, my sort method 
throws an exception.  In addition I do not want to "default" the 
"SortOrder" to the last one used.  Thus, I want the Action to reset the 
"SortOrder" every time.  Since the form contains other properties, I can 
not reset the form.

As an example:
I have 2 Actions, EmployeeAction and TruckAction.
Valid values for "SortOrder" in EmployeeAction are "id, name, hireDate". 
 Valid values for "SortOrder" in TruckAction are "id, purchaseDate, and 
mileage".

Unfortunately, you'll have to provide it.  ActionForms don't carry the
name they were declared with.  The only object with that information
is FormBeanConfig.
There's no surefire failproof way to know what name, if any, is
associated with a DynaActionForm with just an instance of it.
What are you trying to do?  There may be other (better) ways to do
what you're trying to without messing with FormBeanConfigs and
FormPropertyConfigs.

Hubert,
Where do I get the name of the form?

Well, it ain't that easy:
       // code taken from DynaActionFormClass
       DynaActionForm formBean = (DynaActionForm) form;
       FormBeanConfig config =
ModuleUtils.getInstance().getModuleConfig(request).findFormBeanConfig("myFormName");
       FormPropertyConfig props[] = config.findFormPropertyConfigs();
       for (int i = 0; i < props.length; i++) {
           if ("fieldName".equals(props[i].getName())) {
               formBean.set(props[i].getName(), props[i].initial());
               break;
           }
       }
