本來是可以透過得。後來可能改了顛東西。但後來都改回來了。可是還是相同得問題。
下邊是報得 異常:
javax.servlet.ServletException: Base is null: tab_channel_check_configMidControl
javax.faces.webapp.FacesServlet.service(FacesServlet.java:202)
org.apache.myfaces.component.html.util.ExtensionsFilter.doFilter(ExtensionsFilter.java:122)


root cause

搜了好多國外得論壇,也有類似的問題,可是都沒有一個有效得解決方法。
同事做了一個可以用得程式,可是原封不動得配置到我這時,出現了相同得錯誤~!
很鬱悶壓~!難道是系統環境得問題~!
