您好，我正在開發一個使用Oracle ADF和jdeveloper11.1.2.4的Web應用程序。其實我有一個頁面的查詢和表單。搜索和一切都很好，但第一次加載頁面時是空的。它看起來不太好。所以我的想法是這種形式應該是最初不可見的，並且只有在用戶點擊搜索從（af：query）中的搜索按鈕後才應該可見。在adf Query中單擊搜索按鈕後如何使表單可見？
請幫助我。我如何才能做到這一點。
在此先感謝。
以下是我.jsf代碼

的follwoing SI我的Java類代碼
public void customSearch(QueryEvent queryEvent) {
// Add event code here...
System.out.println("in custom srch");
AdfFacesContext.getCurrentInstance().getPageFlowScope().put("showForm", true);
invokeEL("#{bindings.KpiSearchCriteriaQuery.processQuery}", new Class[] { QueryEvent.class },
new Object[] { queryEvent });
System.out.println("end custom srch");
}
感謝您的時間馬庫斯。我嘗試了你的答案。我遵循每一步。 customSearch（QueryEvent queryEvent）方法正常工作。手段SerchCriteria正在工作。但是這種可見性解決方案並不適用。 – Abdul
我已經設置窗體可見=＃{pageFlowScope.updateORDeleteBean.showForm}。我有複製粘貼上面的代碼。但能見度並未開啓或關閉。 – Abdul
你需要在panelFormLayout上設置一個局部觸發器，指向af：詢問 –
