Yeah, but what if the length of the field changes? Where is the maximum length of the field identified? Is it in the HTML page? If so, then you have to go and change the HTML whenever the field changes. With my thin-veneer JSP approach, the input tag is formatted by the infrastructure, which means changes to the field don't affect the HTML. You identify the attributes of the fields in the dictionary (also known as the AppFactory) and that is what is used to build the HTML. Joe
