FormHelpTemplate

public class FormTemplate
extends Template

Template class for substituting default values into html forms. This class is used by the TemplateHandler. The default values in form elements are replaced by the request property that matches the field name. The following field elements are processed:

• <input name=x value=y>
• <input type=input name=x value=y>
• <input type=radio name=x value=y>
• <option value=x>

In all cases, the value attribute must be present. additional information is provided below.

If the enclosing <form> tag has the attribute "prepend", then "prepend" is tacked on the front of each variable name before its value is looked-up. The "prepend" attribute is then removed from the form tag.
