    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.

        public void tag_slash_form​(RewriteContext hr)
        Forget about the "prepend" value
      • tag_input

        public void tag_input​(RewriteContext hr)
        Look for <input name=[x] value=[v]> and replace the value with the entry in the request properties. If no value is supplied, no substitution is done. If value contains any ${..} constructs, the substituted value is used instead of the value in the corrosponding request property.

        public void tag_select​(RewriteContext hr)
        Remember the variable name for the next group of option tags.

      • tag_option

        public void tag_option​(RewriteContext hr)
        Look at the option tag, set the "selected" attribute as needed. In order for this to work, the VALUE tag *must* be used Do ${...} substitutions on the value.
