Question

I am using JSF2, Richfaces4 and Spring. I have a command link. On execute I save records and on complete I execute search to display records like following code. Problem is that fireSearch() in oncomplete executes even if there is a validation error in form. I need to execute fireSearch() only when the record get saved successfully.

只有在验证成功之后我才能完全完成呢?

<a4j:commandLink styleClass="button" action="#{myBean.save}" render="detail_form" execute="@form" oncomplete="fireSearch()">
<span> Save </span>
</a4j:commandLink>

Richfaces 支持在 oncompreful 属性中基于请求的 EL 评估。因此您应该能够打印 < a href=" http://docs.oracle.com/javaee/6/api/javax/faces/context/facesContext.html#isValidationFailed% 28%29"\\\ code> facesContext#isvalidationFailed () , 仿佛它是 JS的条件一样。

例如,

oncomplete="if (#{!facesContext.validationFailed}) fireSearch()"

如果审定失败,最终将导致

oncomplete="if (false) fireSearch()"

因此,该函数不会被援引。
