These tags are going to be reused many times throughout our application, and I prefer to omit this type of decision logic from the jsp pages. Therefore I think it pays to design custom tags to accomplish what I need.
I have been looking at some of the source code for the various tag handlers that extend BaseTagHandler, and I see there is a lot going on. I would like to make sure to leverage all of the functionality included in BaseTagHandler. I was wondering if there is some documentation out there for creating new BaseTagHandler extensions, or custom Struts HTML components in general. I understand how to create taglibs in general, I am asking whether there is such specific documentation for Struts.

The "registration.jsp" page is used for both "Create a New User" and "Log In As Existing User"., but only in the latter case does it show the table at the bottom. This is controlled by the following tag around the table: <logic:equal name="RegistrationForm" property="action" scope="request" value="Edit"> ... </logic:equal> which makes sure that the "action" property on the "RegistrationForm" bean equals "Edit" before displaying the table.
