images

[Michael McGrady <mi...@michaelmcgrady.com>]

PROJECT

I am trying to build an imaging "module" for Struts, etc, buttons.  What 
this does is to use dynamic data on buttons, e.g. color, size, style, 
font, language, etc., and to create the buttons on the fly.  This is, of 
course, done with JSP taglibs. 

PROBLEM

My problem is that I extend the Struts SubmitTag and add various 
properties, very much akin to the ImageTag in Struts.  Additional to the 
ImageTag properties, I add txtClr and bgClr properties as well as 
txtClrCode and bgClrCode properties.  The former allow us to hardcode 
colors of images (buttons) and the latter to provide a dynamic value 
depending on what is in a container referenced with a mapBean property 
that is saved in session scope.  When I use the code (txtClrCode and 
bgClrCode) properties, I eventually set them to txtClr and bgClr before 
writing to the response object.  Also, I only use txtClrCode and 
bgClrCode is txtClr and bgClr are null.

ANOMALY

All the properties are set to null in my ImageTag class.  Yet, after the 
initial value of a tag is set, changing the value of either the 
txtClrCode or the bgClrCode is not working because somehow txtClr and 
bgClr are not being reset to null as expected. 

QUESTION

The computer is always right, so anyone know what I am doing wrong here?

Thanks

Michael McGrady
