单击 adf 查询中的搜索按钮后如何使表单可见？
How make form visible after clicking search button in adf Query?
您好，我正在使用 Oracle ADF 和 jdeveloper11.1.2.4 开发 Web 应用程序。实际上，我有一个包含以下查询和表单的页面。搜索和一切都很好，但是当页面第一次加载时是空的。它看起来不太好。所以我的想法是这个表单最初应该是不可见的，只有在用户点击 Search from(af:query) 中的搜索按钮后才应该可见。
请帮帮我。我该如何实现。
提前致谢。

invokeEL("#{bindings.KpiSearchCriteriaQuery.processQuery}", new Class[] { QueryEvent.class },
new Object[] { queryEvent });
System.out.println("end custom srch");
}
只有当用户按下 "Search" 按钮时，您才能在 panelFormLayout 上将 "visible" 属性 设为 true:
<af:panelFormLayout visible="#{pageFlowScope.showForm}">
为此，您需要覆盖 af:query 的 "queryListener" 方法：
<af:query queryListener="#{yourBean.customSearch}"/>
在您的 YourBean.java 中，您将拥有：
public void customSearch(QueryEvent queryEvent) {
AdfFacesContext.getCurrentInstance().getPageFlowScope().put("showForm", true);
//call your original queryListener- the one you changed in page:
invokeEL("#{bindings.DepartmentsViewCriteriaQuery.processQuery}", new Class[] { QueryEvent.class },
new Object[] { queryEvent });
}
