// Check and see if the pin number is missing
if(pinNumber == null || pinNumber.length() == 0) {
String pinNumberLabel = resources.getMessage( "label.pinnumber" );
// Create an error message for the missing pingNumber value
ActionError newError =
new ActionError("global.error.login.requiredfield", "Pin Number");
errors.add(ActionErrors.GLOBAL_ERROR, newError);
}
// Return the ActionErrors, in any.
return errors;
On page 22 of chapter 3 of the preview book. What is
the `pinNumberLabel' all about?
I think the chapter 3 is very big. There is lot to take in.
ValueObject side bar could be reserved for a latter chapter.
Also I think for JSP side of thing. How does the Page designer
or person who has to rigourous follow an e-style guide look and feel
get into the picture?
Hints and tips for using Struts could be helpful.
Web architecture diagram.
May be a UML diagram might help here.

Subject: Re: DynaActionForm problem with non-string objects
I think that you'll have to extend the framework. The "initial" value is
really designed to be a primitive or one of the wrappers around it. The
ConvertUtils "convert" method is used and it's not really capable of doing
what you want it to do. I think you might take a look at extending the
FormPropertyConfig class, rather than the DynaActionForm. The
DynaActionForm uses a Map already and should be capable of dealing with
Objects. It's the initialization portion of the process that you need to
override and I believe that starts in the FormPropertyConfig class.
