<form jwcid="loginForm@tacos:AjaxForm" updateComponents="ognl:{'loginForm'} listener="listener:userLogin"> 改成
<form jwcid="loginForm@tacos:AjaxForm"> <a jwcid="@tacos:AjaxSubmit" updateComponents="ognl:{'nameDisplay'}" effects="template:{highlight:{any:'[255,255,184], 500, 500'}}"> Login </a> 改成 <a jwcid="@tacos:AjaxSubmit" listener="listener:userLogin" updateComponents="ognl:{'nameDisplay'}" effects="template:{highlight:{any:'[255,255,184], 500, 500'}}"> Login </a> 把fieldset标签关掉，tacos对标签的关闭很严格，自己多检查检查。 |
