From the workbench example, We know that Tapestry is able to indicate a ValidField being Invalid by writing a CSS class, for example "field-error", with the "writeAttributes" method in the delegate class of a specified form. However, for some purpose, the ValidField initially has its own CSS class "normal". It may be rendered as following in normal situation:
<input ... class="normal"/> When an error is detected, the delegate class will render the ValidField like: <input .. class="normal" class="field-error"/> Since the "normal" class is kept, the "field-error" takes no effect at all. Would you please tell me how to make this class take effect or remove the "normal" class. Best wishes, Andy -- [EMAIL PROTECTED] 偶爾投影在妳的波心 ----偶然.徐志摩
