jsf commandLink没有'；t在第一次单击中调用backingbean方法

我的表单中有一个按钮，其代码如下：

<p:commandButton value="#{msgs['message.report.button.search.show']}"
     icon="ui-icon-image" id="searchBtn"
     process="@this"
     actionListener="#{sixteenFormController.search()}"
     update=":assetListForm">
</p:commandButton>

谢谢。

这可能与该问题有关。看看如何解决这个问题，例如，在链接中：

我使用primefaces。这个问题是为莫哈雷特·梅特准备的。这是所有JSF实现的规范和问题。您可以查看、、其中p:commandButton-primefaces组件的问题。
