JSF鏈接不工作

Question

我有一個附件的表單。當我試圖查看我的文檔，它正在做表單驗證，並要求填寫各自的字段，但我不想驗證表單來查看我的file.I已經改變了鏈接從hcommand鏈接到acommand鏈接，並嘗試了更多。但它不工作。可以有人幫助我。 我的代碼是

<h:form id="mailForm"> 
       <span class = "clasMpnlErr" style="color:Blue"><h:messages id="mailFormErrorMessages" for="mailForm"/></span> 
       <table width="100%">

您可以通過屬性「立竿見影」設置爲true跳過驗證。

例如

<h:commandLink immediate="true" value="" action="" /> 

詳細說明如何即時屬性適用於：
